[GIT pull] irq updates for 4.3

[Thomas Gleixner <tglx@linutronix.de>]

Linus,

please pull the latest irq-urgent-for-linus git tree from:

   git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git irq-urgent-for-linus

Three trivial commits:

   - Fix a kerneldoc regression

   - Export handle_bad_irq to unbreak a driver in next

   - Add an accessor for the of_node field so refactoring in next does
     not depend on merge ordering

Thanks,

	tglx
