Subject: ALSA: hda - Fix headset support and noise on HP EliteBook 755 G2
commit f883982dc1b117f04579f0896821cd9f2e397f94 upstream.
HP EliteBook 755 G2 with ALC3228 (ALC280) codec [103c:221c] requires
the known fixup (ALC269_FIXUP_HEADSET_MIC) for making the headset mic
working. Also, it suffers from the loopback noise problem, so we
should disable aamix path as well.
