Subject: [PATCH] ASoC: msm8916-wcd-analog: Fix error handling in pm8916_wcd_analog_spmi_probe
Date: Wed, 16 Mar 2022 04:19:24 +0000 [thread overview]
Message-ID: <20220316041924.17560-1-linmq006@gmail.com> (raw)
In the error handling path, the clk_prepare_enable() function
call should be balanced by a corresponding 'clk_disable_unprepare()'
call , as already done in the remove function.
Fixes: de66b3455023 ("ASoC: codecs: msm8916-wcd-analog: add MBHC support")
