[PATCH] ide: ide-scsi fails to call idescsi_check_condition for things like "Medium not present"
This patch started life as a response to fedora specific ide subsystem changes
that made error handling of my ATAPI tape drive fail; the specifics are in
https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=160868
The insertion of the statement rq->errors = err; near the end of
ide_end_drive_cmd() in drivers/ide/ide-io.c means that rq->errors does not
contain what it needs to in idescsi_end_request() in drivers/scsi/ide-scsi.c
anymore. Recent mainline kernels now also have this change.
The patch below makes ide-scsi whole.
