Adding OF binding to genirq.
Version string is setup to the "devicetree".

Compatible string is not setup for now but you can add your
custom compatible string to uio_of_genirq_match structure.

For example with "vendor,device" compatible string:
static const struct of_device_id __devinitconst uio_of_genirq_match[] = {
{ .compatible = "vendor,device", },
{ /* empty for now */ },
};

+ uioinfo = kzalloc(sizeof(*uioinfo), GFP_KERNEL);
kfree in remove?

Oh yes. Missed that one. It should probably look like the "bad0" case in probe().

Yes, freeing uioinfo in uio_pdrv_genirq_remove make sense for CONFIG_OF.

Please correct me if I am wrong dev.of_node is not NULL for OF. I think yes that's why I would prefer to use this construct instead of #ifdef CONFIG_OF.

if (pdev->dev.of_node)
kfree(pdev->dev.platform_data);

What do you think?
