Merge tag 'pinctrl-v4.6-4' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl
Pull pinctrl fix from Linus Walleij:
"A single last pin control fix for v4.6. t's tagged for stable and
only hits a single driver with two added lines so should be safe.
Tested in linux-next.
- The pull up/down logic for the AT91 PIO4 controller was tilted: we
need to mask the reverse pull when unmasking a pull direction.
Setting both pull up & pull down is illegal and makes no sense"
* tag 'pinctrl-v4.6-4' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl:
pinctrl: at91-pio4: fix pull-up/down logic
