3.18-stable review patch. If anyone has any objections, please let me know.
------------------
From: Takashi Iwai <tiwai@suse.de>
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.
