Subject: [PATCH 4.4 117/146] ALSA: hda - Fix the headset mic jack detection on Dell machine

4.4-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Woodrow Shen <woodrow.shen@...il.com>

commit f83c32925d45926cd0e0f18bf28e6039116c4486 upstream.

The new Dell laptop with codec 3246 can't detect headset mic when
headset was inserted on the machine. So adding pin configurations
into quirk table makes headset mic work correctly.

Codec: Realtek ALC3246
Vendor Id: 0x10ec0256
Subsystem Id: 0x10280781
