From: ChanWoo Lee <cw9316.lee@xxxxxxxxxxx>
In commit 031312dbc695 ("scsi: ufs: ufs-qcom: Remove unnecessary goto statements")
the error handling was accidentally changed, resulting in the error of
ufs_qcom_clk_scale_*() calls not being returned.
This is the case I checked.
* ufs_qcom_clk_scale_notify -> 'ufs_qcom_clk_scale_up_/down_pre_change' error -> return 0;
Let's make sure those errors are properly returned.
