Subject: [PATCH] ASoC: rt5682: move clk related code to rt5682_i2c_probe
Date: Wed, 29 Sep 2021 13:43:44 +0800	[thread overview]
Message-ID: <20210929054344.12112-1-jack.yu@realtek.com> (raw)

The DAI clock is only used in I2S mode, to make it clear
and to fix clock resource release issue, we move CCF clock
related code to rt5682_i2c_probe to fix clock
register/unregister issue.
