Date: Sun, 19 Oct 2014 19:49:45 +0200 From: Stefan Hengelein <stefan.hengelein@....de> To: linux-arm-kernel@...ts.infradead.org Cc: linux-kernel@...r.kernel.org, kaloz@...nwrt.org, khalasa@...p.pl, linux@....linux.org.uk, arnd@...db.de, Stefan Hengelein <stefan.hengelein@....de> Subject: [PATCH] ARM: ixp4xx: remove compilation warnings in io.h When arch/arm/mach-ixp4xx/common-pci.c is compiled, two warnings occur: arch/arm/mach-ixp4xx/include/mach/io.h:144: warning: passing argument 1 of '__raw_readb' makes pointer from integer without a cast arch/arm/mach-ixp4xx/include/mach/io.h:79: warning: passing argument 2 of '__raw_writeb' makes pointer from integer without a cast Both functions expect an 'volatile void __iomem *' but get an u32. The 'u32 addr' variable is initialized with the address of an 'volatile void __iomem *' pointer. Passing the pointer directly, avoids the warning and semantics are preserved. This warning was found with vampyr.
