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.
