[PATCH 2/2] regulator: don't compare raw GPIO descriptor pointers

[Bartosz Golaszewski]

From: Bartosz Golaszewski <bartosz.golaszewski@xxxxxxxxxx>

There's no API contract saying that two GPIO descriptor pointers
obtained with a call to gpiod_get() (or one of the variants), that refer
to the same physical GPIO pin, always point to the same structure. Use
the dedicated comparator function.
