Subject: MIPS: lantiq: make use of __gpio_to_irq
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=6a88a0f762a61f212d4bbcf1ad45369f28014484;p=deliverable%2Flinux.git

MIPS: lantiq: make use of __gpio_to_irq

The gpio_chip struct allows us to set a .to_irq callback. Once this is set
we can rely on the generic __gpio_to_irq() function to map gpio->irq allowing
more than one gpio_chip to register an interrupt
