4.2.8-ckt5 -stable review patch. If anyone has any objections, please let me know. ---8<------------------------------------------------------------ From: Takashi Iwai <redacted> 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.
