Merge tag 'pinctrl-v3.15-4' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl
Pull pinctrl fix from Linus Walleij:
"A single last pinctrl fix for the v3.15 series: the vt8500 driver was
failing to update the output value when the combined set direction
output and set value was executed"
* tag 'pinctrl-v3.15-4' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl:
