Subject: ASoC: mediatek: Drop superfluous PCM preallocation error checks
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=15486e63e7ce2794e6b82843ac6c57146080d98b;p=linux.git

ASoC: mediatek: Drop superfluous PCM preallocation error checks

snd_pcm_lib_preallocate_pages() and co always succeed, so the error
check is simply redundant.  Drop it.
