Merge tag 'gpio-v4.8-3' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio

Pull GPIO fixes from Linus Walleij:
 "Some GPIO fixes that have been boiling the last two weeks or so.
  Nothing special, I'm trying to sort out some Kconfig business and
  Russell needs a fix in for -his SA1100 rework.

  Summary:

   - Revert a pointless attempt to add an include to solve the UM allyes
     compilation problem.

   - Make the mcp23s08 depend on OF_GPIO as it uses it and doesn't
     compile properly without it.

   - Fix a probing problem for ucb1x00"
