Subject: ALSA: hda - Fix headset mic detection problem for several Dell laptops

From: Hui Wang <hui.wang@canonical.com>

commit 3f640970a41429f0a076c01270bbd014c9eae61c upstream.

One of the laptops has the codec ALC256 on it, applying the
ALC255_FIXUP_DELL1_MIC_NO_PRESENCE can fix the problem, the rest
of laptops have the codec ALC295 on them, they are similar to machines
with ALC225, applying the ALC269_FIXUP_DELL1_MIC_NO_PRESENCE can fix
the problem.
