-Subject: scsi: ufs: Clear UAC for RPMB after ufshcd resets
-
-From: Randall Huang <huangrandall@google.com>
-
-[ Upstream commit 1918651f2d7e8d58c9b7c49755c61e41ed655009 ]
-
-If RPMB is not provisioned, we may see RPMB failure after UFS
-suspend/resume. Inject request_sense to clear uac in ufshcd reset flow.
