Subject: [PATCH] Revert "of/irq: make of_irq_find_parent static"

This reverts commit 52493d446141b07c8ba28dd6a529513f8b2342bd.

I have a patch series that is under review that makes use of of_irq_find_parent()

The affected patch is this:

	https://lkml.org/lkml/2015/11/25/291

Is it wrong to use this function? If yes, what's the alternative?
If no, OK to revert?

Thanks,
Qais
