Subject: ALSA: hda - Restore GPIO1 properly at resume with AD1984A
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=4012ade9338c05428162e85cc9b149dcadf1ce85;p=openwrt%2Fstaging%2Fblogic.git

ALSA: hda - Restore GPIO1 properly at resume with AD1984A

The commit 099db17e66294b02814dee01c81d9abbbeece93e introduced a
regression at suspend/resume where the GPIO1 bit isn't properly
restored, thus the speaker output gets muted initially after resume.

The fix is simple, use the cached write for storing GPIO data.
