Subject: [PATCH 02/10] regulator: lm363x: Let core handle GPIO descriptor
Date:   Wed, 28 Nov 2018 11:43:42 +0100
Message-Id: <20181128104350.31902-3-linus.walleij@linaro.org>
In-Reply-To: <20181128104350.31902-1-linus.walleij@linaro.org>
References: <20181128104350.31902-1-linus.walleij@linaro.org>
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

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

Fixes: b2d751b7f69b ("regulator: lm363x: Pass descriptor instead of GPIO number")
