[PATCH v2] ufs: qcom: Properly clear hba priv on failure

From: Bjorn Andersson
Date: Sun Nov 20 2016 - 01:35:02 EST


ufs_qcom_init() sets the hba priv data before attempting to acquire the
phy handle, so make sure to clear this in the case of an error. Failing
to do this will make ufs_qcom_setup_clocks() operate on the uninitalized
host object.
