[alsa-devel] [PATCH 2/2] ALSA: hda - Fix pop noises on reboot for Dell XPS 13 9333

[Gabriele Mazzotta]

If nid 0x15 (Headphone Playback Switch) is in D3 and headphones are
plugged in when the laptop reboots, a pop noise is generated.
Prevent this by keeping nid 0x15 in D0 when headphones are plugged in.
