Subject: [PATCHv1 07/14] power: supply: bq24257: fix race-condition in sysfs registration
Date: Mon, 1 Oct 2018 00:03:42 +0200 [thread overview]
Message-ID: <20180930220349.10515-8-sebastian.reichel@collabora.com> (raw)
In-Reply-To: <20180930220349.10515-1-sebastian.reichel@collabora.com>
This registers custom sysfs properties using the native functionality
of the power-supply framework, which cleans up the code a bit and
fixes a race-condition. Before this patch the sysfs attributes were
not properly registered to udev.
