[SCSI] Recognize missing LUNs for non-standard devices
Some non-standard SCSI targets or protocols, such as USB UFI, report "no LUN present" by setting the Peripheral Device Type to 0x1f and the Peripheral Qualifier to 0 (not 3 as the standard requires) in the INQUIRY response. This patch (as650b) adds a new target flag and code to accomodate such targets. Signed-off-by: Alan Stern <stern@rowland.harvard.edu> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
