[GIT PULL] gpio: fixes for v5.12-rc3

[Bartosz Golaszewski]

Linus,

Here's a bunch of fixes for the GPIO subsystem. We have two regressions in the
core code spotted right after the merge window, a series of fixes for ACPI GPIO
and a subsequent fix for a related regression in gpio-pca953x + a minor tweak
in .gitignore and a rework of handling of the gpio-line-names to remedy a
regression in stm32mp151.

Please pull!

Best Regards,
Bartosz Golaszewski

  gpiolib: Read "gpio-line-names" from a firmware node (2021-03-08 11:59:17 +0100)

----------------------------------------------------------------
gpio fixes for v5.12-rc3

- fix two regressions in core GPIO subsystem code: one NULL-pointer dereference
  and one list corruption
- read GPIO line names from fwnode instead of using the generic device
  properties to fix a regression on stm32mp151
- fixes to ACPI GPIO and gpio-pca953x to handle a regression in IRQ handling
  on Intel Galileo
- update .gitignore in GPIO selftests
