Subject: [PATCH] scsi: ufs: qcom: stop ignoring hibern8 exit failures
Date: Sun, 29 Mar 2026 18:35:14 +0000 [thread overview]
Message-ID: <20260329183514.133412-1-objecting@objecting.org> (raw)
Right now, we're blindly returning success even if waking the link fails during clock scaling. This is a mess because the core then tries to send SCSI commands to a dead link, causing huge timeouts.
Just return the actual error so the core can catch the failure and roll back properly.
