commit 2f4a784f40f8d337d6590e2e93f46429052e15ac upstream.
Move ufshcd_set_variant call in ufs_hisi_init_common to common error section at end of the function, and then jump to this from the error checking statements for both devm_reset_control_get and ufs_hisi_get_resource. This fixes the original commit (63a06181d7ce) which was reverted due to the University of Minnesota problems.
