Subject: ALSA: hda - Fix AFG power management on IDT 92HD* codecs
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=f73d35853e9263c7c404f0d6c0fe3d83fc6fd5c0;p=GitHub%2FLineageOS%2Fandroid_kernel_samsung_universal7580.git

ALSA: hda - Fix AFG power management on IDT 92HD* codecs

The AFG pin power-mapping isn't properly set for the fixed I/O pins
on IDT 92HD* codecs.  This resulted in the low power mode after the
boot until any jack detection is executed, thus no output from the
speaker.

This patch fixes the power mapping for the fixed pins, and also fixes
the GPIO bits and digital I/O pin settings properly in stac92xx_ini().
