ALSA: x86: Cache AUD_CONFIG register value At enabling the audio, we modify AUD_CONFIG register bit 0. So far, it does read-modify-write procedure with a special hack for the channel bits due to the silicon bug. But we can optimize it by remembering the AUD_CONFIG register value privately. This simplifies the things a lot. Signed-off-by: Takashi Iwai <tiwai@suse.de>
