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"
