Subject[PATCH 3.4 081/176] ALSA: hda - Fix wrong gpio_dir & gpio_mask hint setups for IDT/STAC codecs
Date
From: Takashi Iwai <tiwai@suse.de>

3.4.107-rc1 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.
