From: Takashi Iwai Date: Thu, 27 Oct 2011 23:16:55 +0000 (+0200) Subject: ALSA: hda - Manage unsol tags in hda_jack.c X-Git-Tag: accepted/tizen/common/20141203.182822~4454^2~116^2~13^2~11 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=3a93897ea37cbb8277f8a4232c12c0c18168a7db;p=platform%2Fkernel%2Flinux-arm64.git ALSA: hda - Manage unsol tags in hda_jack.c Manage the tags assigned for unsolicited events dynamically together with the jack-detection routines. Basically this is almost same as what we've done in patch_sigmatel.c. Assign the new tag number for each new unsol event, associate with the given NID and the action type, etc. With this change, now all pins looked over in snd_hda_jack_add_kctls() are actually enabled for detection now even if the pins aren't used for jack-retasking by the driver.
