ALSA: hda - Reduce the suspend time consumption for ALC256
ALC256 has its own quirk to override the shutup call, and it containsthe COEF update for pulling down the headset jack control. Currently,the COEF update is called after clearing the headphone pin, and thisseems triggering a stall of the codec communication, and results in along delay over a second at suspend.A quick resolution is to swap the calls: at first with the COEFupdate, then clear the headphone pin.Fixes:4a219ef ("ALSA: hda/realtek - Add ALC256 HP depop function")Bugzilla:https://bugzilla.kernel.org/show_bug.cgi?id=198503Reported-by: Paul Menzel <pmenzel@molgen.mpg.de>Cc: <stable@vger.kernel.org>Signed-off-by: Takashi Iwai <tiwai@suse.de>
