* ASoC: fsl_sai: Sort local variable in general wayNicolin Chen2013-12-211-7/+7
| | | | | | | | | | | | | | | | | Generally we would write code for local variable like: static new_func() { struct xxx *yyy; ... int ret; } But this driver only follows this pattern for some functions, not all. Thus this patch sorts the local variable in the general way.

* ASoC: fsl_sai: Make dev_err information neaterNicolin Chen2013-12-211-12/+4
| | | | | | | | | Since using dev_err() there's no need to mention SAI any more, it will print the full name of the driver -- fsl_sai. Signed-off-by: Nicolin Chen <Guangyu.Chen@freescale.com> Reviewed-by: Xiubo Li <Li.Xiubo@freescale.com> Signed-off-by: Mark Brown <broonie@linaro.org>

* ASoC: fsl_sai: Drop useless channels check in hw_params()Nicolin Chen2013-12-211-4/+1
| | | | | | | | | SAi only supports two data channels on hardware level and the driver also does register the min->1 and max->2, so no need to check channels.
