In order to build drivers/irqchip/irq-bcm7038-l1.c as a module (for use
in GKI), we need to export_to_desc() which is used in this snippet of
code:

	irqd_set_single_target(irq_desc_get_irq_data(irq_to_desc(virq)));

This effectively reverts 64a1b95bb9fe ("genirq: Restrict export of
irq_to_desc()").

No. I'm not reexporting this. We've spent quite some time to prevent all
kind of drivers for fiddle with irq descriptors and I'm not going
to reopen that can of worms.

irq_get_irq_data() is exported and provides you what you need.

That is exactly what I was looking for and somehow missed it during my 
search the other day, thanks!
