From 14f437a1d7b49a2e873f63436526f9aed3a781c3 Mon Sep 17 00:00:00 2001 From: Benjamin Tissoires Date: Mon, 27 Mar 2017 16:59:35 +0200 Subject: HID: logitech-hidpp: rename battery level into capacity The power_supply term for the percentage is capacity. Capacity level can be given when non accurate mileage is provided by the device, so better stick to the terms used in power_supply.
