ARM: 5745/1: Change ep93xx gpio_irq static inlines to macros
From: Ryan Mallon <ryan@bluewatersys.com> Change the gpio_to_irq and irq_to_gpio static inline functions to macros so that they can be used in variable initialisers. Signed-off-by: Ryan Mallon <ryan@bluewatersys.com> Acked-by: H Hartley Sweeten <hsweeten@visionengravers.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
