Subject: [PATCH] ARM: s3c24xx: avoid warning for inb/outb
Date: Thu, 25 Feb 2016 23:04:50 +0100 [thread overview]
Message-ID: <1456437900-853667-1-git-send-email-arnd@arndb.de> (raw)
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.
