[PATCH 5.15 114/230] ASoC: rt5682: move clk related code to rt5682_i2c_probe

Greg Kroah-Hartman

From: Jack Yu <jack.yu@realtek.com>

[ Upstream commit 57589f82762e40bdaa975d840fa2bc5157b5be95 ]

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.
