[GIT PULL] GPIO fixes for the v3.19 series

[Linus Walleij]

Hi Linus,

here is a set of fixes that mainly appeared when Johan Hovold
started exercising the removal path of the GPIO library, dealing
with hotplugging of GPIO controllers.

Please pull it in!

Yours,
Linus Walleij

  gpiolib: of: Correct error handling in of_get_named_gpiod_flags
(2015-01-15 18:31:47 +0100)

----------------------------------------------------------------
A slew of fixes dealing with some irritating bugs (non-regressions)
that have been around forever in the GPIO subsystem, most of them
also tagged for stable:

- A large slew of fixes from Johan Hovold who is finally testing and
  reviewing the removal path of the GPIO drivers.

- Fix of_get_named_gpiod_flags() so it works as expected.

- Fix an IRQ handling bug in the crystalcove driver.
