Merge tag 'gpio-v3.17-4' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio
Pull gpio fixes from Linus Walleij:
"Two GPIO fixes:
- GPIO direction flags where handled wrong in the new descriptor-
based API, so direction changes did not always "take".
- Fix a handler installation race in the generic GPIO irqchip code"
* tag 'gpio-v3.17-4' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio:
gpio: Fix potential NULL handler data in chained irqchip handler
gpio: Fix gpio direction flags not getting set
