Subject: [PATCH] ALSA: hda/realtek - Add default procedure for suspend and resume state
Git-commit: c2d6af53a43fd8bb528eac8f31ffb666e9c74cf7
Patch-mainline: 4.13-rc1
References: bsc#1052235

Except ALC269.
This will reduce pop noise from headset or headphone.
If codec enter to power save state, when plug headset or headphone....
It has a chance to cut off power by system.
Our new codec use this procedure will be more stable during suspend
and resume state.
