I merged the irq core patches into git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git irq/for-gpio This branch can be pulled into the GPIO tree to avoid pull request dependencies. Thanks, tglx

I side with Thomas: thanks for working hard and doing the right thing here where many would have given up. It's exactly this deep integration of new drivers that make the kernel provide such great infrastructure and clean drivers. Now I feel I need to understand this think good enough to spot the second driver that needs to do this already during early review ... Yours, Linus Walleij
