Subject: [PATCH] of: irq: Export of_irq_count()

From: Thierry Reding <treding@...dia.com>

of_irq_count() is handy for obtaining the number of interrupts assigned
to a device tree node. It is reasonable to want to access this function
from loadable modules, so export the symbol to allow that.

Hi Rob, Frank,

This patch is required for the new Tegra186 GPIO driver I'm trying to
get merged for v4.12. It'd be great if I could get an Acked-by from you
so that the patch can be merged through the GPIO tree along with a few
other prerequisites for the new driver.

Potential for conflicts is rather minimal given the line count.

Thanks,
Thierry
