This is how mach/gpio.h ends up looking - two things:
1. is there any reason for asm/irq.h and linux/io.h in there? 2. asm/gpio.h already includes asm-generic/gpio.h and defines the dispatchers for the trivial case.
So, I think this is how it should look:
#ifndef __MACH_U300_GPIO_H #define __MACH_U300_GPIO_H #include <mach/hardware.h> #endif
Or even just:
/* empty */ if mach/hardware.h include is not required for ARCH_NR_GPIOS.
