From: Hui Wang hui.wang@canonical.com Date: Fri, 22 Dec 2017 11:17:44 +0800 Subject: ALSA: hda - Add MIC_NO_PRESENCE fixup for 2 HP machines
From: Hui Wang hui.wang@canonical.com
commit 322f74ede933b3e2cb78768b6a6fdbfbf478a0c1 upstream.
There is a headset jack on the front panel, when we plug a headset into it, the headset mic can't trigger unsol events, and read_pin_sense() can't detect its presence too. So add this fixup to fix this issue.
