[alsa-devel] [PATCH 0/6] ASoC: PCM format type conversion fixes
Hi, the PCM format is a fixed type with __bitwise, and it needs cast or other trick to deal with integer. This is a series of such fixes for ASoC.

Many drivers calling snd_mask_set() need to do ugly cast with __force for shutting up the sparse warnings. Actually almost all of them are about setting the format, so it's far better to provide a common helper snd_mask_set_format() to pass SNDRV_PCM_FORMAT_* directly without the cast. There are a few other calls of snd_mask_set(), but they are in the PCM core code, so we leave them for now.

The example code in dpcm.rst contains an open code calling snd_mask_set(), and this can be better represented with params_set_format() instead. This automatically fixes the sparse warning about snd_pcm_format_t handling, too.

As sparse warns, the PCM format type can't be dealt as integer as found in Intel SST driver codes. Fix them in the following two ways: - The open code with snd_mask_set() and params->masks reference is replaced with params_set_format() - The rest codes with snd_mask_set(fmt, SNDRV_PCM_FORMAT_XXX) are replaced with the new helper, snd_mask_set_format().

Nice! Should I just apply all these (including the initial patch adding the helper)?

The patch ASoC: dmaengine: Use standard pcm_format_to_bits() macro has been applied to the asoc tree at https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git 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.

As sparse warns, the PCM format type can't be dealt as integer as found in Intel SST driver codes. Fix them in the following two ways: - The open code with snd_mask_set() and params->masks reference is replaced with params_set_format() - The rest codes with snd_mask_set(fmt, SNDRV_PCM_FORMAT_XXX) are replaced with the new helper, snd_mask_set_format().

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.

The example code in dpcm.rst contains an open code calling snd_mask_set(), and this can be better represented with params_set_format() instead. This automatically fixes the sparse warning about snd_pcm_format_t handling, too.

Many drivers calling snd_mask_set() need to do ugly cast with __force for shutting up the sparse warnings. Actually almost all of them are about setting the format, so it's far better to provide a common helper snd_mask_set_format() to pass SNDRV_PCM_FORMAT_* directly without the cast. There are a few other calls of snd_mask_set(), but they are in the PCM core code, so we leave them for now.
