Subject: [PATCH 10/10] power: supply: olpc_battery: Have the framework register sysfs files for us
Date: Sun, 10 Mar 2019 17:24:19 +0100	[thread overview]
Message-ID: <20190310162419.11861-11-lkundrak@v3.sk> (raw)
In-Reply-To: <20190310162419.11861-1-lkundrak@v3.sk>

The power framework gained ability to register groups of sysfs
attributes in commit cef8fe6a382c ("power: supply: core: add support for
custom sysfs attributes").
