[PATCH] uio_pdrv_genirq: get irq through platform resource if not set otherwise

From: Benedikt Spranger
Date: Mon May 14 2012 - 12:48:25 EST


Platform devices are configured through platform resources. The interrupt
in the driver uio_pdrv_genirq is instead configured through a side channel
i.e. the platform data structure. Make it possible to use the generic
configuration scheme via platform resource.
