From mboxrd@z Thu Jan 1 00:00:00 1970 From: Arnd Bergmann Subject: [PATCH] ARM: s3c24xx: avoid warning for inb/outb Date: Thu, 25 Feb 2016 23:04:50 +0100 Message-ID: <1456437900-853667-1-git-send-email-arnd@arndb.de> Return-path: Sender: linux-kernel-owner@vger.kernel.org To: Kukjin Kim , Krzysztof Kozlowski Cc: linux-arm-kernel@lists.infradead.org, Arnd Bergmann , linux-samsung-soc@vger.kernel.org, linux-kernel@vger.kernel.org List-Id: linux-samsung-soc@vger.kernel.org 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.
