[PATCH] SCSI: Don't be so verbose if no disc is present

[PATCH] SCSI: Don't be so verbose if no disc is present

[Daniel Drake]

[-- Attachment #1: Type: text/plain, Size: 442 bytes --]

Running a simple "touch /dev/scd0" on a SCSI cdrom will cause the following 
message to appear in the logs if no disc is present:

	Device not ready. Make sure there is a disc in the drive.

This results in the logs being flooded for some users by those userspace 
agents which repeatedly poll the device for media change.

This patch demotes the message to a quieter scsi-logging message only.
