ARM: pxa: armcore: fix PCI PIO warnings
The it8152 PCI host used on the pxa/cm_x2xx machines uses the old-style I/O window registration. This should eventually get converted to pci_ioremap_io() but for now, let's cast the IT8152_IO_BASE constant to an integer type to get rid of the warnings. Without this patch, building cm_x2xx_defconfig results in: arch/arm/common/it8152.c: In function 'it8152_pci_setup': arch/arm/common/it8152.c:287:18: warning: assignment makes integer from pointer without a cast [enabled by default] arch/arm/common/it8152.c:288:16: warning: assignment makes integer from pointer without a cast [enabled by default] arch/arm/common/it8152.c:291:17: warning: assignment makes integer from pointer without a cast [enabled by default] Signed-off-by: Arnd Bergmann <arnd@arndb.de> Acked-by: Igor Grinberg <grinberg@compulab.co.il> Cc: Bjorn Helgaas <bhelgaas@google.com> Cc: Krzysztof Halasa <khc@pm.waw.pl> Cc: Mike Rapoport <mike@compulab.co.il> Cc: Haojian Zhuang <haojian.zhuang@gmail.com> Cc: Eric Miao <eric.y.miao@gmail.com>
