Merge tag 'pinctrl-v3.15-3' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl
Pull pin control fixes from Linus Walleij:
"Here is a small set of pin control fixes for the v3.15 series. All
are individual driver fixes and quite self-contained. One of them
tagged for stable.
- Signedness bug in the TB10x
- GPIO inversion fix for the AS3722
- Clear pending pin interrups enabled in the bootloader in the
pinctrl-single driver
- Minor pin definition fixes for the PFC/Renesas driver"
