Subject: ALSA: pcm: Remove unused functions declaration
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=adc2ae0bb6daa2287d1a6567d18be01da546f7a7;p=openwrt%2Fstaging%2Fblogic.git

ALSA: pcm: Remove unused functions declaration

Remove function declarations for functions that don't have a matching
implementation.

For snd_pcm_build_linear_format the implementation was removed in
64d27f96cb719cf8 ("[ALSA] Support 3-bytes 24bit format in PCM OSS
emulation"). All the others never had one (as far as git history goes).
