This is automatically handled by pci. Drop it. This might be needed on machines if the BIOS turns intx off during boot. However, there's no evidence of such behavior for ahci and the only such case seems to be ICH5 PATA according to ata_piix. Also, given the way ahci operates, it's highly unlikely BIOS ever disables IRQ for the controller. However, as this change has slight possibility of introducing failure, please schedule it for #upstream. Signed-off-by: Tejun Heo Signed-off-by: Jeff Garzik 1
