ALSA: hda - restore the gpio led after resume On some HP laptops, the mute led is controlled by codec gpio. When some machine resume from s3/s4, the codec gpio data will be cleared to 0 by BIOS: Before suspend: IO[3]: enable=1, dir=1, wake=0, sticky=0, data=1, unsol=0 After resume: IO[3]: enable=1, dir=1, wake=0, sticky=0, data=0, unsol=0 To skip the AFG node to enter D3 can't fix this problem. A workaround is to restore the gpio data when the system resume back from s3/s4. It is safe even on the machines without this problem.
