[alsa-devel] [PATCH 00/20] ALSA: Drop superfluous PCM preallocation error checks

[Takashi Iwai]

Hi,

this is yet another patchset for trivial cleanups.
At this time, it's about the superfluous error check from
snd_pcm_lib_preallocate_pages() and co.  They always succeed and never
return a failure although many codes do the error check.  The patches
simply remove the error checks and finally change the function to be
void function.

The patches are applied on top of my previous NULL device fix patches,
so not applicable to ASoC tree, I guess.  As all these are trivial,
applying through my tree altogether would be simpler.

So, Mark, please give your ACK if the changes to ASoC drivers are OK.


thanks,

Takashi
