Subject: irqchip: omap-intc: remove unnecesary of_address_to_resource() call
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=8bb3b375c8837ea73740883a90b1d7719b2653cc;p=linux-beck.git

irqchip: omap-intc: remove unnecesary of_address_to_resource() call

of_iomap(), which is called from omap_init_irq_of(),
already takes care of making sure we have a valid
resource to deal with. Because of that, we can
safely remove our explicit call to of_address_to_resource().
