[v3,3/4] ASoC: SOF: Intel: hda: Modify existing helper to disable WAKEEN

Commit Message

Kai-Heng Feng Jan. 12, 2021, 1:07 p.m. UTC

Modify hda_codec_jack_wake_enable() to also support disable WAKEEN.
In addition, this patch also moves the WAKEEN disablement call out of
hda_codec_jack_check() into hda_codec_jack_wake_enable().

This is a preparation for next patch.

No functional change intended.
---
v3:
 No change.
v2:
 Mention it moves the disabling part into another function.
