ALSA: hda - Fix silent headphone on Thinkpads with AD1984A codec
AD1984A codec has a couple of pins with EAPD controls, and the generic codec driver tries to turn each of them on/off depending on the pin active state. However, Thinkpads seem to use EAPD of the speaker pin as a master EAPD for controlling the mute of all outputs, including the headphone. This results in the dead headphone output via the headphone plugging because it mutes the speaker and turns off EAPD. The fix is to simply add spec->gen.keep_on_eapd flag. [This is a regression fix on 3.12 where we moved the AD codec parser to the generic parser. 3.11 and earlier didn't show this problem because still static quirks have been used.] Reported-and-tested-by: Vito Caputo <vcaputo@gnugeneration.com> Signed-off-by: Takashi Iwai <tiwai@suse.de>
