Subject: [PATCH] ASoC: rt5682: Fix regulator enable/disable sequence
Date: Sat, 30 Sep 2023 17:55:50 +0800 [thread overview]
Message-ID: <tencent_4F37C9B5315B7960041E8E0ADDA869128F08@qq.com> (raw)
This will attempt to disable the regulators if the initial enable fails
which is a bug.
Fix this bug by modifying the code to the correct sequence.
