Subject: [RFC PATCH 6/7] hwmon: lm90: simplify using devm_regulator_get_enable()
Date: Wed, 10 Aug 2022 14:32:18 +0300 [thread overview]
Message-ID: <4565950ddca2f78209dad49e169d4af7517db27e.1660127865.git.mazziesaccount@gmail.com> (raw)
In-Reply-To: <cover.1660127865.git.mazziesaccount@gmail.com>
[-- Attachment #1: Type: text/plain, Size: 1996 bytes --]
Drop open-coded pattern: 'devm_regulator_get(), regulator_enable(),
add_action_or_reset(regulator_disable)' and use the
devm_regulator_get_enable().
