Subject: [PATCH RFC 6/7] staging: iio: impedance-analyzer: admv1013: Use devm_regulator_get_enable_get_voltage()
Date: Wed, 27 Mar 2024 18:18:55 -0500 [thread overview]
Message-ID: <20240327-regulator-get-enable-get-votlage-v1-6-5f4517faa059@baylibre.com> (raw)
In-Reply-To: <20240327-regulator-get-enable-get-votlage-v1-0-5f4517faa059@baylibre.com>
We can reduce boilerplate code by using
devm_regulator_get_enable_get_voltage().
