Subject: PCI: fix pci_ioremap_bar() on s390
X-Git-Tag: firefly_0821_release~17185^2
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=96499871f45b9126157b1a5c512d6e30f1635225;p=firefly-linux-kernel-4.4.55.git

PCI: fix pci_ioremap_bar() on s390

s390 doesn't have ioremap_*, so protect the definition of the new
pci_ioremap_bar function with CONFIG_HAS_IOMEM to avoid build breakage.
