UIO: uio_pdrv_genirq: allow custom irq_flags
Mike Frysinger [Wed, 29 Oct 2008 22:35:52 +0000 (18:35 -0400)]
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.
