Subject: [ALSA] hda-codec - Fix default pin config of Abit AW9D-MAX
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=f95474ec05106a2af46220fbf8624adc17fcb3e7;p=openwrt%2Fstaging%2Fblogic.git

[ALSA] hda-codec - Fix default pin config of Abit AW9D-MAX

Fix the default pin configuration of Abit AW9D-MAX.  The board has a
broken BIOS that doesn't set the correct pin default configs, which
screws up the auto-configuration of snd-hda-intel driver.
The patch enables the override of default pin config values.
