The function snd_soc_new_pcms() was removed during the
multi-component refactoring in commit f0fba2ad1b6b ("ASoC:
multi-component - ASoC Multi-Component Support").  Its PCM creation
role is now handled by soc_new_pcm(), which was later moved to
sound/soc/soc-pcm.c by commit ddee627cf6bb ("ASoC: core - Separate
out PCM operations into new file.").

In fsl_dma.c, update the comment to reference soc_new_pcm().  Also
remove the stale paragraph about snd_dma_alloc_pages() always
allocating in lowmem, since commit e159704f7920 ("ASoC: fsl_dma:
Use managed buffer allocation") replaced that call with
snd_pcm_set_fixed_buffer_all().

In siu_pcm.c, remove the stale comment referencing
snd_soc_new_pcms() and the no-longer-existing socdev structure.

v3:
 - Drop "via the pcm_construct callback" from fsl_dma.c comment (Mark Brown)

v2:
 - Also fix the stale comment in siu_pcm.c

Applied to

Thanks!

[1/1] ASoC: update outdated comments for removed snd_soc_new_pcms()
      https://git.kernel.org/broonie/sound/c/3e839947b842

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
