[PATCH 2/7] gpio: omap: switch to use platform_get_irq

From: Grygorii Strashko
Date: Tue Aug 18 2015 - 07:12:29 EST


Switch OMAP GPIO driver to use platform_get_irq(), because
it is not recommened to use platform_get_resource(pdev, IORESOURCE_IRQ, ..)
for requesting IRQ resources any more, as they can be not ready yet
in case of DT-boot.
