[alsa-devel] [RFC 2/5] ALSA: HDA: create HDA common lib

Vinod Koul vinod.koul at intel.com
Sun Mar 8 15:37:56 CET 2015


From: Jeeja KP <jeeja.kp at intel.com>

Move the common hda controller and hda codec code from sound/pci/hda/ to
sound/hda. This new location will serve as common HDA lib uses by current
code as well as upcoming ASoC HDA implementations
