Subject: ASoC: nuc900: Remove unnecessary snd_pcm_lib_preallocate_free_for_all()
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=3a96878e6d01b70836cbf8a0e968619ef2e2aceb;p=openwrt%2Fstaging%2Fblogic.git

ASoC: nuc900: Remove unnecessary snd_pcm_lib_preallocate_free_for_all()

The ALSA core takes care that all preallocated memory is freed when the PCM
itself is freed. There is no need to do this manually in the driver.
