[GIT PULL] GPIO fixes for v4.9

[Linus Walleij]

Hi Linus,

here is a set of patches for the v4.9 series. A bunch of stuff
hardening the GPIO userspace ABI is targeted for stable, and
stands out as especially important.

Apart from that is is just regular first-pull-after mergwindow fixes
with some targeted for stable and some fixing the v4.9 HEAD.

Details are in the signed tag.

Please pull it in!

Yours,
Linus Walleij

  gpio: mpc8xxx: Correct irq handler function (2016-10-24 02:20:40 +0200)

----------------------------------------------------------------
Here is a set of GPIO fixes for the v4.9 kernel series:

- Fix up off-by one and line offset validation, info leak to
  userspace, and reject invalid flags. Those are especially
  valuable hardening patches from Lars-Peter Clausen, all tagged
  for stable.

- Fix module autoload for TS4800 and ATH79.

- Correct the IRQ handler for MPC8xxx to use handle_level_irq()
  as it (A) reacts to edges not levels and (B) even implements
  .irq_ack(). We were missing IRQs here.

- Fix the error path for acpi_dev_gpio_irq_get()

- Fix a memory leak in the MXS driver.

- Fix an annoying typo in the STMPE driver.

- Put a dependency on sysfs to the mockup driver.
