[PATCH 1/2] i2c: i2c-ocores: Add irq support for sparc

From: Andreas Larsson
Date: Tue Oct 23 2012 - 12:56:05 EST


There are no platform resources of type IORESOURCE_IRQ on sparc, so the irq
number is acquired in a different manner for sparc. The general case uses
platform_get_irq, that internally still uses platform_get_resource.
