No, what you want to get rid of is the #include <linux/gpio.h> not the
<linux/gpio/driver.h>, we want to be more specific. Sorry for putting the
comment wrong.

This doesn't apply to my tree :O

My EP93XX_GPIO_LINE_MAX_IRQ is in
arch/arm/mach-ep93xx/include/mach/gpio-ep93xx.h

So I think you must be having another patch somewhere in the ARM SoC
tree. (I can take it, just send it along with an update of this one.)
