Date: Thu, 25 Feb 2016 23:04:50 +0100 From: Arnd Bergmann <arnd@...db.de> To: Kukjin Kim <kgene@...nel.org>, Krzysztof Kozlowski <k.kozlowski@...sung.com> Cc: linux-arm-kernel@...ts.infradead.org, Arnd Bergmann <arnd@...db.de>, linux-samsung-soc@...r.kernel.org, linux-kernel@...r.kernel.org Subject: [PATCH] ARM: s3c24xx: avoid warning for inb/outb s3c24xx implements its own inb/outb macros, but the implementation prints warnings when the port number argument is not a 32-bit scalar: drivers/scsi/pas16.c: In function 'NCR5380_pwrite': arch/arm/mach-s3c24xx/include/mach/io.h:193:68: warning: cast to pointer from integer of different size [-Wint-to-pointer-cast] #define __ioaddrc(port) ((__PORT_PCIO(port) ? PCIO_BASE + (port) : (void __iomem *)(port))) This slightly modifies the definition of the __ioaddrc macro to avoid the warning.
