cppcheck warning: sound/soc/samsung/s3c24xx_simtec.c:191:7: style: Variable 'ret' is assigned a value that is never used. [unreadVariable] ret = snd_soc_dai_set_clkdiv(cpu_dai, S3C24XX_DIV_PRESCALER, ^ Looking at the code, it's not clear why the return value is checked in the two other cases but not here, so mirror the behavior and add a check.
