Stafford Horne 405ea6d706 openrisc: io: Define iounmap argument as volatile ... [ Upstream commit 52e0ea9002 ] When OpenRISC enables PCI it allows for more drivers to be compiled resulting in exposing the following with -Werror. drivers/video/fbdev/riva/fbdev.c: In function 'rivafb_probe': drivers/video/fbdev/riva/fbdev.c:2062:42: error: passing argument 1 of 'iounmap' discards 'volatile' qualifier from pointer target type drivers/video/fbdev/nvidia/nvidia.c: In function 'nvidiafb_probe': drivers/video/fbdev/nvidia/nvidia.c:1414:20: error: passing argument 1 of 'iounmap' discards 'volatile' qualifier from pointer target type drivers/scsi/aic7xxx/aic7xxx_osm.c: In function 'ahc_platform_free': drivers/scsi/aic7xxx/aic7xxx_osm.c:1231:41: error: passing argument 1 of 'iounmap' discards 'volatile' qualifier from pointer target type Most architectures define the iounmap argument to be volatile. To fix this issue we do the same for OpenRISC. This patch must go before PCI is enabled on OpenRISC to avoid any compile failures.
