In ufshcd-priv.h , the function name of all vop wrapping APIs have the same prefix "ufshcd_vops", I need to use the same format as them.
As for return the gear value as the function result. In our original design, we also return gear result for this function, but finally we want to use return value to indicate the status , e.g,, if vendor doesn't implement this vop, we return -EOPNOTSUPP , if there is no matched gear to the freq , we return -EINVAL. Although we didn't check the return value in this series, we still want to preserve this extensibility in case this function be used to other where in the future.
