[alsa-devel] [PATCH] ALSA: hda - Fix the headset mic jack detection on Dell machine

[woodrow.shen at canonical.com]

From: Woodrow Shen <woodrow.shen at gmail.com>

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
