do not override the error code from davinci_mcasp_get_dt_params(), jut
jump to err.

I have ever thought this point. I can't make sure it's necessary, davinci_mcasp_get_dt_params always return 0 now.
If it's necessary, I can submit a new patch to fix it. Look forward to your reply sincerely.

Thanks, best wish!

right.
davinci_mcasp_get_dt_params() should be void and we don't need the check
in probe for return value.

auxclk-fs-ratio is optional property.
