This change updates the 3ware raid drivers to use scsi_scan_target(),

direct, even if it is a tiny bit more code in the driver.
if it doesn't support luns scsi_add_device sounds like the better
interface to use.
That applies to 3w-xxxx, certainly.
I don't see a strong argument for scsi_add_device() over
scsi_scan_target(), though. scsi_scan_target() directly supports the
generic struct device/class_device stuff, and supports both wildcard LUN
scans as well as no-LUN targets. My vague preference would be to use
scsi_scan_target() unless there is a strong reason not to...
How does 3x-9xxx support luns? From reading the
code it doesn't seem to support passthru and faking up LUNs for logical
volumes sounds odd.
