From 7639a06c23c7d4cda34c2546bd7290d8753849ca Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Tue, 3 Mar 2015 10:07:24 +0100 Subject: ALSA: hda - Move a part of hda_codec stuff into hdac_device Now some codes and functionalities of hda_codec struct are moved to hdac_device struct. A few basic attributes like the codec address, vendor ID number, FG numbers, etc are moved to hdac_device, and they are accessed like codec->core.addr. The basic verb exec functions are moved, too.
