Subject: [GIT PULL] irq updates for 3.18

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 fixlets from the ARM SoC camp:
 - Correct irqdomain initialization for atmel-aic
 - Correct error handling for device tree parsing in bcm controllers

Thanks,

	tglx
