+Subject: scsi: sr: Return appropriate error code when disk is ejected
+
+From: ManYi Li <limanyi@uniontech.com>
+
+[ Upstream commit 7dd753ca59d6c8cc09aa1ed24f7657524803c7f3 ]
+
+Handle a reported media event code of 3. This indicates that the media has
+been removed from the drive and user intervention is required to proceed.
+Return DISK_EVENT_EJECT_REQUEST in that case.
