Thanks! I will send a v2 since I have to fix a typo in the Subject.

In the original code this big (unsigned) value was added as parent IRQ and
things wouldn't work, with the proposed change IRQ won't work, but at least
in robust way without any surprises (whatever big parent IRQ number mean).

I think the people who have access to hardware and different configurations
of the kernel may or may not add the support later on.
