[GIT PULL] GPIO fixes for v4.9

[Linus Walleij]

Hi Linus,

here is a bunch of GPIO fixes for the v4.9 series.

The most prominent thing is the largeish file descriptor leak fix,
and the regression fix for multiple-instance chips is pretty important
too.

Please pull it in!

Yours,
Linus Walleij

  gpio/mvebu: Use irq_domain_add_linear (2016-11-01 19:31:49 +0100)

----------------------------------------------------------------
Some GPIO fixes for the v4.9 series:

- Fix a nasty file descriptor leak when getting line handles.

- A fix for a cleanup that seemed innocent but created a problem
  for drivers instantiating several gpiochips for one single
  OF node.

- Fix a unpredictable problem using irq_domain_simple() in the
  mvebu driver by converting it to a lineas irqdomain.
