From: Takashi Iwai Date: Fri, 15 Jun 2012 12:34:42 +0000 (+0200) Subject: ALSA: hda - Use common codes for ATI, Nvidia and VIA simple codecs X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=d0b1252d;p=linux-beck.git ALSA: hda - Use common codes for ATI, Nvidia and VIA simple codecs The code refactoring using the same helper functions for sharing the codes among ATI, Nvidia and VIA simple_hdmi* stuff. Except for that spec->pcm_playback is no longer pointer, the functionality doesn't change.
