119-122: 🩺 Stability & Availability | 🟡 Minor | ⚡ Quick win

Restore the Bluetooth address fallback when qcom_serial_number is unavailable.

qcom_socinfo_driver and the qcom,wcn7860-bt serdev path have no ordering dependency. If qca_uart_setup() reaches generate_bdaddr_from_serial() before qcom_socinfo_probe() assigns the serial, the helper returns -EINVAL, and the commented-out qca_check_bdaddr() fallback is not used. Bluetooth setup can fail.

In
`@patch/kernel/archive/sm8750-7.2/0030-leds-Add-driver-for-HEROIC-HTR3212.patch`:
- Around line 307-322: Update the probe error handling around htr3212_probe so
failures from devm_regmap_init_i2c, htr3212_init_regs, or htr3212_parse_dt
branch to one shared cleanup path that deasserts sdb and disables vdd before
returning the error; preserve the successful probe path.
- Around line 287-289: Handle every devm_gpiod_get() and
devm_gpiod_get_optional() failure immediately with dev_err_probe() instead of
retaining ERR_PTR values; in
patch/kernel/archive/sm8750-7.2/0030-leds-Add-driver-for-HEROIC-HTR3212.patch
lines 287-289, update the HEROIC HTR3212 probe GPIO acquisition, and in
patch/kernel/archive/sm8750-7.2/0031_input--Add-driver-for-RSInput-Gamepad.patch
lines 493-512, update the RSInput Gamepad GPIO acquisitions and unwind the
enabled regulator before returning.
- Around line 60-69: Include <linux/regulator/consumer.h> with the other headers
so the regulator APIs used by the driver are declared.

In
`@patch/kernel/archive/sm8750-7.2/0031_input--Add-driver-for-RSInput-Gamepad.patch`:
- Line 298: Update the status-frame length guard around the handler parsing
FRAME_POS_DATA_1 through FRAME_POS_DATA_14 to require payload_length >= 14
before reading any fields. Preserve the existing checksum validation and parsing
behavior for complete payloads.
- Around line 423-439: Update the serdev receive handling around
rsinput_process_data and the persistent rx_buf state to accumulate bytes across
callbacks, resynchronize on frame headers, and parse each complete
length-delimited frame independently. Retain incomplete trailing data for the
next callback, while validating each complete frame’s checksum before processing
it; do not treat the entire callback as a single frame.
- Line 228: Update the write path containing serdev_device_write_buf so it
verifies the returned byte count against frame_len; retry until the entire frame
is queued, or return an error for a short/failed write instead of treating every
non-negative result as success.

In
`@patch/kernel/archive/sm8750-7.2/0046-arm64-dts-qcom-Add-AYN-CQ8725S-Common.patch`:
- Around line 1173-1179: Update the WCN7860 regulator properties in the affected
device-tree node to provide all names required by qca_soc_data_wcn7860:
vddio-supply, vddaon-supply, vdddig-supply, vddrfa0p8-supply, vddrfa1p2-supply,
and vddrfa1p9-supply. Map each property to the corresponding existing board
rail, and remove or replace the Wi-Fi-only supply names from this node.

In
`@patch/kernel/archive/sm8750-7.2/0048-drm-msm-dsi-reparent-byte-pixel-src-to-xo-on-disable.patch`:
- Around line 44-47: Update the source-clock reparenting logic around the
byte_src_parent and pixel_src_parent checks to capture both clk_set_parent()
return values and stop before disabling link clocks when either fails. Preserve
runtime power and link-clock state on failure, or safely roll back any
successful reparent before returning the error.

In
`@patch/kernel/archive/sm8750-7.2/0060-ASoC-qcom-sc8280xp-enable-MI2S-bit-clock-on-BE-startup.patch`:
- Line 76: Update the startup function around qcom_snd_sdw_startup to store its
return value, and when it fails for an MI2S DAI, decrement mi2s_clk_count and
disable i2s_clk when the count reaches zero before returning the error.

In
`@patch/kernel/archive/sm8750-7.2/0063-ASoC-wcd939x-route-usbss-on-integrated-jack-insert.patch`:
- Around line 150-151: Update the callback containing wcd939x_usbss_audio_config
to return and propagate its configuration error, preventing or retrying MBHC
plug detection when USBSS routing fails. Also resolve the qcom,usbss phandle as
a probe dependency so initialization does not silently continue without the
provider.

In
`@patch/kernel/archive/sm8750-7.2/0072-ASoC-lpass-rx-macro-add-HPH-PCM-mode.patch`:
- Line 57: Prevent HPH PCM mode changes while audio paths are active: in
patch/kernel/archive/sm8750-7.2/0072-ASoC-lpass-rx-macro-add-HPH-PCM-mode.patch
lines 57-57, update the control handler around rx->is_pcm_enabled to reject
changes when a non-AUX interpolator is active, or atomically update
pcm_select_users and CDC_RX_TOP_SWR_CTRL; in
patch/kernel/archive/sm8750-7.2/0073-ASoC-wcd939x-add-HPH-PCM-HiFi-mode.patch
lines 468-468, reject changes while either HPH DAPM path is active, or
synchronize the codec and SoundWire transition.

In
`@patch/kernel/archive/sm8750-7.2/0073-ASoC-wcd939x-add-HPH-PCM-HiFi-mode.patch`:
- Around line 153-156: Update wcd939x_hph_pcm_dac_teardown() to clear only the
HPHL or HPHR compander enable bit selected by hphr, rather than both
WCD939X_CDC_COMP_CTL_0_HPHL_COMP_EN and WCD939X_CDC_COMP_CTL_0_HPHR_COMP_EN.
Preserve the independent operation of the RDAC1 and RDAC2 teardown paths.

In `@patch/kernel/archive/sm8750-7.2/0500-ROCKNIX-set-boot-fanspeed.patch`:
- Line 10: Update the Odin 3 boot fan initialization around set_pwm and
pwm_fan_probe so the device-specific boot PWM matches the cooling curve’s
maximum state, and ensure ctx->pwm_fan_state is updated to that programmed value
to prevent later maximum-state requests from returning early.

In
`@patch/kernel/archive/sm8750-7.2/0603-ASoC-codecs-wcd939x-keep-the-codec-resumed-while-a-ja.patch`:
- Around line 40-43: Update the MBHC startup flow around wcd_mbhc_start so that
if startup returns an error, both wcd->rxdev and wcd->txdev have
pm_runtime_allow called before returning the error. Preserve the forbidden
runtime-PM state on successful startup.

In
`@patch/kernel/archive/sm8750-7.2/0606-phy-qcom-qmp-pcie-switch-pipe-clk-mux-to-phy.patch`:
- Around line 39-41: Update qmp_pcie_power_on so a nonzero return from
clk_set_rate on qmp->pipe_clks[0].clk is propagated through the existing
power-on cleanup path instead of only being logged, while preserving the
successful path when the switch succeeds.

In
`@patch/kernel/archive/sm8750-7.2/1001-haptics-driver-support-periodic-sine-and-fixes.patch`:
- Line 128: Update haptics_upload_effect() so the active-update early return and
the recursive converted-sine upload return do not retain the outer runtime-PM
reference acquired by haptics_runtime_resume_get(); either evaluate these
branches before acquiring it or release the reference before returning, while
preserving their existing return behavior.

In
`@patch/kernel/archive/sm8750-7.2/1004-input-qcom-hv-haptics-defer-rsinput-playback.patch`:
- Line 62: Protect the phapchip lookup and global_playback_work scheduling with
a shared global lifetime lock, rather than relying on READ_ONCE(phapchip).
During removal, clear phapchip while holding that lock, release it before
cancel_work_sync(), and ensure callers cannot schedule work after removal has
begun.

Restore the Bluetooth address fallback when qcom_serial_number is unavailable.

qcom_socinfo_driver and the qcom,wcn7860-bt serdev path have no ordering dependency. If qca_uart_setup() reaches generate_bdaddr_from_serial() before qcom_socinfo_probe() assigns the serial, the helper returns -EINVAL, and the commented-out qca_check_bdaddr() fallback is not used. Bluetooth setup can fail.

A serdev receive callback can contain a frame fragment or multiple frames. This code validates the whole callback as one frame. It drops short fragments and rejects coalesced frames because the final checksum does not validate the complete callback.

Maintain a persistent receive length. Append bytes to rx_buf, locate headers, and process each complete length-delimited frame while retaining an incomplete suffix.

READ_ONCE(phapchip) does not protect the lifetime of chip. A caller can obtain chip, removal can clear phapchip and finish cancel_work_sync(), and the caller can then schedule global_playback_work. The work can access released device state.

Use a global lifetime lock around the phapchip lookup and scheduling operation. Clear phapchip under the same lock before cancel_work_sync().

- Line 10: Update the Odin 3 boot fan initialization around set_pwm and
pwm_fan_probe so the device-specific boot PWM matches the cooling curve’s
maximum state, and ensure ctx->pwm_fan_state is updated to that programmed value
to prevent later maximum-state requests from returning early.

Preserve unique MAC addresses for multiple pdevs.

generate_macaddr_from_serial() derives the MAC address only from the global qcom_serial_number. The serial-success branch reverses and registers that same value for every pdev without applying ar->pdev_idx. Add stable per-pdev derivation before registration.

291-292: 🩺 Stability & Availability | 🟡 Minor | ⚡ Quick win

Publish qcom_serial_number only after soc_device_register() succeeds.

qcom_serial_number points to a devm_kasprintf() buffer. If soc_device_register() fails, qcom_socinfo_probe() returns without calling qcom_socinfo_remove(), and devres releases the buffer while the global pointer remains non-NULL. The Bluetooth and ath12k paths then pass that stale pointer to strlen(), which can cause a use-after-free crash. Move the assignment after the IS_ERR(qs->soc_dev) check, or clear it before every failed return.

Quiesce asynchronous callbacks before freeing chip.

haptics_remove() does not cancel hbst_off_timer, stop_work, or set_gain_work. A pending callback can dereference chip after devm teardown. Cancel the timer and synchronously cancel both work items before clearing phapchip and unregistering the device.

Preserve negative IRQ errors, including -EPROBE_DEFER.

platform_get_irq_byname() returns a negative error on failure, but this check only detects zero. The driver then passes the negative value to devm_request_threaded_irq() and converts a deferred or missing IRQ into a generic request failure. Return the original error when fifo_empty_irq < 0.

Do not call sleepable force-feedback callbacks under event_lock.

These wrappers hold a spinlock while calling ff->upload, ff->playback, and ff->erase. The callbacks take mutexes, perform copy_from_user, sleep in usleep_range(), and access regmap or NVMEM. The RSInput bridge can therefore trigger sleeping-in-atomic-context failures or deadlocks. Use a sleepable mutex or remove this spinlock.

40-40: 🎯 Functional Correctness | 🟠 Major | ⚡ Quick win

Set chip_is_playing only after playback starts successfully.

Line 40 marks playback active before haptics_clear_fault() and the hardware writes complete. If an enable operation fails, the restore path leaves chip_is_playing set.

Subsequent playback calls then refuse to start. Upload calls can also enter the active-playback update path while the hardware is stopped.

Set the flag after successful enablement. Clear it on every failed enable path.

Release runtime PM state for unsupported waveforms.

This branch returns after haptics_runtime_resume_get() succeeds. It also bypasses the restore path that clears IGNORE_SWR_IN_SPMI_PLAY.

Repeated unsupported uploads increase the runtime PM usage count and can prevent autosuspend.

Advertise the supported FF_SINE waveform.

The driver accepts FF_SINE, but probe advertises only the generic FF_PERIODIC capability. Standard userspace capability checks will not detect sine support.

Add FF_SINE to the force-feedback capability bitmap.

Process oversized input in rsinput_rx() incrementally.

When the input exceeds the remaining drv->rx_buf capacity, rsinput_rx() clears drv->rx_len and returns count before copying data or calling rsinput_process_data(). This drops retained partial data and any new CMD_STATUS frames. Preserve unprocessed bytes instead of reporting discarded data as consumed. The normal fragmentation and coalescing path remains separate and works while the buffer has capacity.

Cancel queued hBoost-off work before new playback.

Line 6286 separates timer expiration from the regulator disable operation. haptics_wait_hboost_ready() cancels only hbst_off_timer.

If the timer already queued hbst_off_work, a new effect can start before the worker runs. The worker can then disable hBoost during active playback.

Cancel and synchronize hbst_off_work on the playback enable path before the driver reuses hBoost.
