Subject: [GIT PULL] gpio fixes for v6.14-rc7

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

Linus,

Please pull the following GPIO core fixes for the next RC.

The first commit is a backport from my v6.15-rc1 queue that turned out to
be needed in v6.14 as well but as the former diverged from my fixes branch
I had to adjust the patch a bit. I will pull in v6.14-rc7 once tagged and
resolve the conflict between the two.

The second commit fixes a regression observed in user-space where closing
a file descriptor associated with a GPIO device results in a ~10ms delay
due to the atomic notifier calling rcu_synchronize() when unregistering.

Please pull,
Bartosz
