This change added an (empty) IRQ_NONE #define to interrupt.h.

Several scsi drivers are already using an IRQ_NONE. Rename that to
SCSI_IRQ_NONE (a similar change was done in 2.5 by Andrew Morton several
months ago).

I've tested the compilation with 2.4.23-pre2.

Please apply

This change added an (empty) IRQ_NONE #define to interrupt.h.

Several scsi drivers are already using an IRQ_NONE. Rename that to
SCSI_IRQ_NONE (a similar change was done in 2.5 by Andrew Morton several
months ago).

I've tested the compilation with 2.4.23-pre2.
