Subject: [PATCH 05/10] regulator: max8973: Let core handle GPIO descriptor
Date: Wed, 28 Nov 2018 11:43:45 +0100 [thread overview]
Message-ID: <20181128104350.31902-6-linus.walleij@linaro.org> (raw)
In-Reply-To: <20181128104350.31902-1-linus.walleij@linaro.org>
Use the gpiod_get() rather than the devm_* version so that the
regulator core can handle the lifecycle of these descriptors.
Fixes: e7d2be696faa ("regulator: max8973: Pass descriptor instead of GPIO number")
Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
