[PATCH 3.12 031/176] ALSA: hda - Fix wrong gpio_dir & gpio_mask hint setups for IDT/STAC codecs

From: Jiri Slaby <hidden>
Date: 2015-01-29 10:09:18
Also in: lkml
Subsystem: sound, the rest · Maintainers: Jaroslav Kysela, Takashi Iwai, Linus Torvalds

From: Takashi Iwai <redacted>

3.12-stable review patch.  If anyone has any objections, please let me know.

===============

commit c507de88f6a336bd7296c9ec0073b2d4af8b4f5e upstream.

stac_store_hints() does utterly wrong for masking the values for
gpio_dir and gpio_data, likely due to copy&paste errors.  Fortunately,
this feature is used very rarely, so the impact must be really small.
