[PATCH 57/60] UIO: uio_pdrv_genirq: allow custom irq_flags

From: Greg Kroah-Hartman
Date: Tue Jan 06 2009 - 17:34:35 EST


From: Mike Frysinger <vapier@xxxxxxxxxx>

I can't think of a reason why the driver prevents people from setting any
custom bits in their platform device, but I can think of some reasons for
allowing custom flags. Like setting the IRQF_TRIGGER_... bits.
