Subject: [PATCH v3 3/4] ASoC: SOF: Intel: hda: Modify existing helper to disable WAKEEN
Date: Tue, 12 Jan 2021 21:07:01 +0800 [thread overview]
Message-ID: <20210112130704.1201406-3-kai.heng.feng@canonical.com> (raw)
In-Reply-To: <20210112130704.1201406-1-kai.heng.feng@canonical.com>
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.
