[ALSA] hda-codec - Implement auto-mic jack sensing on Samsung laptops
Implemented the auto-mic jack sensing for Samsung laptops with AD1986A codec chip (model=laptop-eapd). The hardware uses pin 0x1d and 0x1f for the internal and external mics, respectively. Signed-off-by: Takashi Iwai <tiwai@suse.de>
