We used to set up the GPIO used for the SMC ethernet IRQ by requesting the GPIO line explicitly. As we recently established that specifying the GPIO controller as interrupt parent and requesting one of its interrupts by reference should be enough, we do away with this. Incidentally, the Nomadik GPIO chip driver handles this just fine: the IRQ is set up and fired as expected. Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
