[PATCH 08/13] scsi: ufs: qcom: Check the return value of ufs_qcom_power_up_sequence()

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



If ufs_qcom_power_up_sequence() fails, then it makes no sense to enable
the lane clocks and continue ufshcd_hba_enable(). So let's check the return
value of ufs_qcom_power_up_sequence().
