[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

----------------------------------------------------------------
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

Hi Linus,

I realized only after I sent out this PR that I had rebased the branch
on top of v5.12-rc2 (because of the v5.12-rc1 situation) without
--rebase-merges and this caused git to drop the merge commit for
Andy's pull-request. Please let me know if you can pull this as is or
if I should rebuild my branch and resend.

Best Regards,
Bartosz Golaszewski

This is fine - it's small, it's a one-time pain, and there's that reason for it.

So as long as Andy is aware of how his patches got rebased and don't
match his branch any more, I think it's not a big deal, and I've
pulled it as-is.

Thanks! It's not big deal, but a good learning anyway how to communicate and
proceed with the git in such (rare I suppose) situations.
