[PATCH] ASoC: wm8960: Fix error handling in probe
by Guenter Roeck 11 Sep '23

11 Sep '23

Commit 422f10adc3eb ("ASoC: wm8960: Add support for the power supplies") added regulator support to the wm8960 driver, but neglected to update error handling in the probe function. This results in warning backtraces if the probe function fails.

[PATCH] ASoC: cs35l56: Call pm_runtime_dont_use_autosuspend()
by Richard Fitzgerald 11 Sep '23

11 Sep '23

Driver remove() must call pm_runtime_dont_use_autosuspend(). Drivers that call pm_runtime_use_autosuspend() must disable it in driver remove(). Unfortunately until recently this was only mentioned in 1 line in a 900+ line document so most people hadn't noticed this. It has only recently been added to the kerneldoc of pm_runtime_use_autosuspend(). THIS WON'T APPLY CLEANLY TO V6.5 AND EARLIER: We will send a separate backported patch to stable.

[PATCH v2] ASoC: soc-pcm: Shrink stack frame for __soc_pcm_hw_params
by Charles Keepax 11 Sep '23

11 Sep '23

Commit ac950278b087 ("ASoC: add N cpus to M codecs dai link support") added an additional local params in __soc_pcm_hw_params, for the CPU side of the DAI. The snd_pcm_hw_params struct is pretty large (604 bytes) and keeping two local copies of it can make the stack frame really large. It is worth noting the variables are in separate code blocks so for some optimisation levels in the compiler these will get automatically combined keeping the stack frame reasonable. But better to manually combine them to cover all cases. Add a single local variable for __soc_pcm_hw_params and use in both loops to shrink the stack frame.

[PATCH 6.5 618/739] um: Fix hostaudio build errors

6.5-stable review patch.
