[alsa-devel] [PATCH v2] ALSA: hda - Fix the headset mic that will not work on Dell desktop machine

[woodrow.shen at canonical.com]

When the headset was plugged in the Dell desktop, the mic of headset can't be detected and workable.
According to the alsa-info, we found the differece between alsa and init_pin_configs
on the machine, so we need to add the pin configs to make headset work.
