Subject: ASoC: rsnd: call clk_prepare()/clk_enable() for AUDIO_CLKx
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=68a550248e295ba548e30c876ccdec351e286eee;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

ASoC: rsnd: call clk_prepare()/clk_enable() for AUDIO_CLKx

ADG can output AUDIO_CLKOUTx, and these are generated from
AUDIO_CLKx. Thus we need to call clk_prepare()/clk_enable()
for AUDIO_CLKx.
