Subject: [PATCH -next] ASoC: fsl_micfil: Remove set but not used variable 'osr'

From: YueHaibing <yuehaibing@...wei.com>

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

sound/soc/fsl/fsl_micfil.c: In function 'get_clk_div':
sound/soc/fsl/fsl_micfil.c:154:6: warning: variable 'osr' set but not used [-Wunused-but-set-variable]

It is never used since introduction in
commit 47a70e6fc9a8 ("ASoC: Add MICFIL SoC Digital Audio Interface driver.")
