An sr device that reports sense data with SK/ASC/ASCQ of 2/4/2 (Not ready, Logical unit not ready, Initializing command required) will be handled in sr_drive_status as (2/4/!1) and assumed to be a 'format in progress' which returns CDS_DISC_OK. The drive will not be made ready in this case. Prior to 210ba1d1 sr_drive_status would have returned CDS_TRAY_OPEN and this results in an START_STOP_UNIT to close the tray, which resolves the initialization requirement. This patch adds handling for SK/ASC/ASCQ of 2/4/2 where it will return CDS_TRAY_OPEN as a means of triggering a START_STOP_UNIT. This issue is seen on the IBM POWER platform when using a file-backed, virtual optical device. The device does not support media queries through the Get Event Status Notification command which could otherwise trigger a START_STOP_UNIT call to close an open tray. Signed-off-by:
