[PATCH] irq: export handle_simple_irq, irq_modify_status and irq_to_desc

From: Jonathan Cameron
Date: Wed Apr 13 2011 - 12:33:26 EST

This is to allow their use in IIO. We have complete control of
both the irq_chip creation and requesting of irqs so would like
to be able to build as a module. That requires these exports.

Signed-off-by: Jonathan Cameron <jic23@xxxxxxxxx>

Exports irq_modify_status in addition to those in the
previous version. This is in response to Thomas'
comments on use of set_irq_flags within drivers.

Exports are now _GPL as requested.
