Subject: [GIT PULL] gpio fixes for v6.19-rc5

Linus,

Here's a set of fixes for the upcoming RC. There are several ordinary
driver fixes and a fix to a race between the registration of two chips
that causes a crash in GPIO core.

The bulk of the changed lines however, concerns the management of shared
GPIOs that landed in v6.19-rc1. Enabling it for ARCH_QCOM enabled it in
defconfig which effectively enabled it for all arm64 platforms and
exposed the code to quite a lot of testing (which is good, right? :)).
I received a number of bug reports, which I progressively fixed over the
course of last weeks. This explains the number of lines higher than what
I normally aim for at this stage.

Please consider pulling.

Thanks
Bartosz

  gpio: shared: fix a false-positive sharing detection with reset-gpios (2026-01-09 09:56:46 +0100)

----------------------------------------------------------------
gpio fixes for v6.19-rc5

- balance superio enter/exit calls in error path in gpio-it87
- fix a race where we try to take the SRCU read lock of the GPIO device
  before it's been initialized causing a NULL-pointer dereference
- fix handling of short-pulse interrupts in gpio-pca053x
- fix a reference leak in error path in gpio-mpsse
- mark the GPIO controller as sleeping (it calls sleeping functions) in
  gpio-rockchip
- fix several issues in management of shared GPIOs
