[PATCH 0/2] gpio: don't compare raw GPIO descriptor pointers directly

[Bartosz Golaszewski]

Handling of shared GPIOs in the kernel needs some improvements. Let's
start with a simple change of not comparing GPIO descriptor pointers
directly as there's nothing that guarantees that the same physical pin
will always be represented by a single GPIO descriptor obtained by
calling gpiod_get().

For merging: I suggest to take patch 1/2 through the GPIO tree and
provide an immutable tag for the regulator tree.
