ALSA: hda - Fix silent output on MacBook Air 1,1
commit e7729a415315fcd9516912050d85d5aaebcededc upstream. Similarly to other Apple products, MBA 1,1 needs a specific quirk. Pin 0x18 must be set to VREF_50 to have sound output. This was no longer done since commit 1a97b7f, resulting in a mute built-in speaker. This patch corrects the regression by creating a fixup for the MBA 1,1. Fixes: 1a97b7f22774 ("ALSA: hda/realtek - Remove the last static quirks for ALC882") Tested-by: Adrien Vergé <adrienverge@gmail.com> Signed-off-by: Adrien Vergé <adrienverge@gmail.com> Signed-off-by: Takashi Iwai <tiwai@suse.de> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
