Merge tag 'gpio-v3.19-5' of git://

Pull gpio fixes from Linus Walleij:
 "Yet more GPIO fixes for the v3.19 series.

  There is a high bug-spot activity in GPIO this merge window, much due
  to Johan Hovolds spearheading into actually exercising the removal
  path for GPIO chips, something that was never really exercised before.

  The other two fixes are augmenting erroneous behaviours in two
  specific drivers for minor systems.

  Summary from signed tag:

   - Two fixes stabilizing that which was never stable before: removal
     of GPIO chips, now let's stop leaking memory.
   - Make sure OMAP IRQs are usable when the irqchip API is used
     orthogonally to the gpiochip API.
   - Provide a default GPIO base for the mcp23s08 driver"
