[RESEND 00/19] Rid W=1 warnings in SCSI

[RESEND 00/19] Rid W=1 warnings in SCSI

[Lee Jones]

[Resending to include the SCSI ML as per Martin's request]

This set is part of a larger effort attempting to clean-up W=1
kernel builds, which are currently overwhelmingly riddled with
niggly little warnings.
