[ALSA] hda-codec - Add Mic Boost control with auto-configuration
Some codecs need Mic Boost mixer controls for obtaining a proper recording level, but the auto-configuration doesn't create them. This patch adds the creation of mic-boost controls on corresponding codecs. Signed-off-by: Takashi Iwai <tiwai@suse.de> Signed-off-by: Jaroslav Kysela <perex@suse.cz>
