From: David Martin <[email protected]>
Greetings,
The following patch was submitted to the lkml in 2004 by David Martin
(http://lkml.org/lkml/2004/12/27/1). It wasn't accepted, but I was
unable to find a reason why, so I'm resending it now.
Without this patch the SCSI ioctl CDROM_DRIVE_STATUS always returns
CDS_TRAY_OPEN even if the tray is closed. This patch fixes that.
