[PATCH 3/4] gpio: ep93xx: remove private irq_to_gpio function

The ep93xx goes through its own back-and-forth dance every time
it wants to know the gpio number for an irq line, when it really
just hardcodes a fixed offset in ep93xx_gpio_to_irq().

This removes the pointless macro and replaces the conversion inside
of the driver with simple add/subtract operations, using an
explicit macro.

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.)
