[PATCH 4.9 35/61] ALSA: hda/realtek - Add some fixes for ALC233

From: Greg Kroah-Hartman
Date: Mon Apr 30 2018 - 15:26:43 EST

4.9-stable review patch. If anyone has any objections, please let me know.


From: Kailang Yang <kailang@xxxxxxxxxxx>

commit ea04a1dbf8b1d6af759d58e705636fde48583f8f upstream.

Fill COEF to change EAPD to verb control.
Assigned codec type.

This is an additional fix over 92f974df3460 ("ALSA: hda/realtek - New
vendor ID for ALC233").

[ More notes:
according to Kailang, the chip is 10ec:0235 bonding for ALC233b,
which is equivalent with ALC255. It's only used for Lenovo.
The chip needs no alc_process_coef_fw() for headset unlike ALC255. ]
