ALSA: hda - Fix the noise after suspend on ALC283 codec
When the power state of ALC283 codec goes to D3, it gives a noise via headphone output. This is because the driver tries to clear all pins via snd_hda_shutup_pins(). Setting the mic pin to zero triggers such a noise. Define a new shutup call specific to this codec and control the pins there more precisely. Also, add the power-save enable/disable sequences in the resume and the new shutup calls. Signed-off-by: Kailang Yang <kailang@realtek.com> Signed-off-by: Takashi Iwai <tiwai@suse.de>
