[alsa-devel] [PATCH -next] ASoC: tlv320aic32x4: Remove set but not used variable 'mclk_rate'

[Yue Haibing]

From: YueHaibing <yuehaibing at huawei.com>

Fixes gcc '-Wunused-but-set-variable' warning:

sound/soc/codecs/tlv320aic32x4.c: In function 'aic32x4_setup_clocks':
sound/soc/codecs/tlv320aic32x4.c:669:16: warning: variable 'mclk_rate' set but not used [-Wunused-but-set-variable]

It is not used since introduction in
commit 96c3bb00239d ("ASoC: tlv320aic32x4: Dynamically Determine Clocking")
