Make few pointers in ASoC functions as pointers to const, so the code is clearer to read, a bit safer and allows further constifications (e.g. placing some data as rodata).

Best regards, Krzysztof

New subject: [PATCH 1/6] ASoC: Constify of_phandle_args in snd_soc_dai_driver

ASoC core code does not modify contents of 'of_phandle_args' in 'struct snd_soc_dai_driver', so the pointer can be made as a pointer to const. This makes code safer, serves as clear annotation of core's intentions and allows putting pointed structures in rodata (if ever applicable).

New subject: [PATCH 3/6] ASoC: Constify passed data to core function

Several ASoC functions receive pointers to data which is not modified, e.g. pointers to 'snd_soc_dai', 'snd_soc_pcm_runtime', 'snd_pcm_hw_params' and 'snd_soc_dai_link'.

All these pointers can be made as a pointer to const. This makes code safer, serves as clear annotation of function's intentions (no ownership passed to the function, no modifications) and allows putting pointed structures in rodata (if ever applicable).

New subject: [PATCH 4/6] ASoC: Constify DAI passed to get_channel_map

get_channel_map() is supposed to obtain map of channels without modifying the state of the given DAI, so make the pointer to 'struct snd_soc_dai' as pointing to const.

New subject: [PATCH 5/6] ASoC: Constify return of snd_soc_dai_get_pcm_stream()

Returned 'struct snd_soc_pcm_stream' by snd_soc_dai_get_pcm_stream() is not modified by the users, so it can be changed as pointer to const. This is a necessary step towards making the 'dai->driver' a pointer to const.

While checking all possible references around ASoC PCM, I apparently ended up there and spotted things to improve. No dependencies, I should sent it separately.

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
