Subject: UIO: uio_pdrv_genirq: allow custom irq_flags
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=e543ae896626a54c0c05e3c434312d6d033d450c;p=deliverable%2Flinux.git

UIO: uio_pdrv_genirq: allow custom irq_flags

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.
