x86: <asm/io.h>: fix outl/outsl access size
outl so far behaved like outb, probably due to a copy-paste error when it was first added. We have three users in-tree for outl: * drivers/serial/serial_ns16550_pci.c only for handling a Quatech qurik, which probably no one ever needed * drivers/serial/serial_ns16550.c For platform drivers with a 4 byte I/O port resource. Only possible user is x86 and that has a 1 byte I/O port resource. Thus no one used this either. * drivers/watchdog/itco_wdt.c Here it indeed triggers a bug, although in my testing the WDAT was functional without. Fix this up so new code doesn't have to track this down. Signed-off-by: Ahmad Fatoum <> Link: Signed-off-by: Sascha Hauer <>
