Subject: [PATCH v2 4/8] power: supply: core: tabularize HWMON temperature labels
Date: Fri, 03 Apr 2020 18:23:32 +0200 [thread overview]
Message-ID: <ae82abf9da86542f5657a8c37106bcdae5011927.1585929579.git.mirq-linux@rere.qmqm.pl> (raw)
In-Reply-To: <cover.1585929579.git.mirq-linux@rere.qmqm.pl>
Rework power_supply_hwmon_read_string() to check it's parameters.
This allows to extend it later with labels for other types of
measurements.
