Subject: [patch] linux/io.h: forward declare struct pci_dev

From: Heiko Carstens <heiko.carstens@...ibm.com>

In file included from arch/s390/mm/ioremap.c:18:
include/linux/io.h:46:
	warning: "struct pci_dev" declared inside parameter list
include/linux/io.h:46:
	warning: its scope is only this definition or declaration,
		 which is probably not what you want

Guess it's time to get rid of ioremap.c on s390 if possible...
