The affected drivers call platform_get_irq() but ignore its result -- they blithely pass the negative error codes to request_irq() which expects *unsinged* IRQ #s. Stop doing that by checking what platfrom_get_irq() returns. [1/3: scsi: jazz_esp: add IRQ check [2/3] scsi: sun3x_esp: fix IRQ check [3/3] scsi: sni_53c710: fix IRQ check
