Subject: [GIT PULL] gpio fixes for v6.14-rc4

From: Bartosz Golaszewski <bartosz.golaszewski@...aro.org>

Linus,

Please pull the following set of GPIO fixes for the upcoming RC. There
are two fixes for GPIO core: one adds missing retval checks to older
code, while the second adds SRCU synchronization to legs in code that
were missed during the big rework a few cycles back. There's also one
small driver fix.

Best Regards,
Bartosz Golaszewski
