Subject[PATCH 4.9 5/9] scsi: sr: Return appropriate error code when disk is ejected
Date
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.
