Subject: [PATCH 01/10] regulator: fixed: Let core handle GPIO descriptor

Use the gpiod_get() rather than the devm_* version so that the
regulator core can handle the lifecycle of these descriptors.

Fixes: efdfeb079cc3 ("regulator: fixed: Convert to use GPIO descriptor only")
Signed-off-by: Linus Walleij <linus.walleij@...aro.org>
