[PATCH 00/23] ASoC: codecs: wcd family: cleanups
Hi,
Set of simple cleanups from similar issues in all Qualcomm WCD93xx codecs.
The first patch "ASoC: codecs: wcd-mbhc: Constify passed MBHC reg fields" is a requirement for few others, but except this they are independent.
Best regards, Krzysztof

Best regards,
The wcd-mbhc-v2 helper code/module does not modify passed array of registry fields, thus it can be made const for code safety. It will also allow individual drivers to allocate the array in rodata.

The driver does not use few 'struct wcd9335_codec' members, so just drop them for smaller code.

wcd9335_parse_dt() function is called only from probe(), so printing errors on resource acquisition is discouraged, because it can pollute dmesg. Use dev_err_probe() to fix this and also make the code a bit simpler.

Error-level should not be used as debugging. The code (function wcd9335_get_dmic_clk_val()) will always be called with same parameters, so this is not really useful debug anyway, so drop it.

Driver was prepared to adjust DMIC microphone parameters according to DMIC clock rate which is read from platform data or Devicetree. The latter part never happened, so the code is always called with dmic_clk_rate=0, prints error and uses default/fallback values. All this part can be simplified by dropping dead parts of code.

Driver stores the voltage of mic bias in fields in state container structure, but actually never reads them - except for the mic2 bias (micb2_mv field). Drop the fields from the structure so the code will be a bit simpler.

Set of simple cleanups from similar issues in all Qualcomm WCD93xx codecs.
The first patch "ASoC: codecs: wcd-mbhc: Constify passed MBHC reg fields" is a requirement for few others, but except this they are independent.

All being well this means that it will be integrated into the linux-next tree (usually sometime in the next 24 hours) and sent to Linus during the next merge window (or sooner if it is a bug fix), however if problems are discovered then the patch may be dropped or reverted.
You may get further e-mails resulting from automated or manual testing and review of the tree, please engage with people reporting problems and send followup patches addressing any issues that are reported if needed.
If any updates are required or you are submitting further changes they should be sent as incremental updates against current git, existing patches will not be replaced.
Please add any relevant lists and maintainers to the CCs when replying to this mail.
Thanks, Mark
