[GIT PULL] late GPIO fixes for v5.9

[Linus Walleij]

Hi Linus,

here is a batch of GPIO fixes for the v5.9 series.

I'm not entirely happy with myself over this, it is too much
and too late. New bugs kept popping up, in hindsight I
should have sent smaller installments, earlier of course.

I blame stuff like stress and weltschmertz and trying to
grok KASan and a few more things on my plate.

Please pull it in.

Yours,
Linus Walleij

  gpio: pca953x: Correctly initialize registers 6 and 7 for PCA957x
(2020-10-01 10:00:18 +0200)

----------------------------------------------------------------
Some late GPIO fixes for the v5.9 series:

- Fix compiler warnings on the OMAP when PM is disabled

- Clear the interrupt when setting edge sensitivity on the
  Spreadtrum driver.

- Fix up spurious interrupts on the TC35894.

- Support threaded interrupts on the Siox controller.

- Fix resource leaks on the mockup driver.

- Fix line event handling in syscall compatible mode
  for the character device.

- Fix an unitialized variable in the PCA953A driver.

- Fix access to all GPIO IRQs on the Aspeed AST2600.

- Fix line direction on the AMD FCH driver.

- Use the bitmap API instead of compiler intrinsics for
  bit manipulation in the PCA953x driver.
