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.
