Subject: [PATCH] ALSA: hda - Reduce the suspend time consumption for ALC256
Git-commit: 1c9609e3a8cf5997bd35205cfda1ff2218ee793b
Patch-mainline: v4.16-rc1
References: bsc#1051510

ALC256 has its own quirk to override the shutup call, and it contains
the COEF update for pulling down the headset jack control.  Currently,
the COEF update is called after clearing the headphone pin, and this
seems triggering a stall of the codec communication, and results in a
long delay over a second at suspend.

A quick resolution is to swap the calls: at first with the COEF
update, then clear the headphone pin.
