Subject: [PATCH] ASoC: rk817: Use devm_clk_get() in rk817_platform_probe
Date: Mon, 4 Apr 2022 09:07:46 +0000 [thread overview]
Message-ID: <20220404090753.17940-1-linmq006@gmail.com> (raw)
We need to call clk_put() to undo clk_get() in the error path.
Use devm_clk_get() to obtain a reference to the clock, It has
the benefit that clk_put() is no longer required.
Fixes: 0d6a04da9b25 ("ASoC: Add Rockchip rk817 audio CODEC support")
