Subject: [PATCH 2/4] ACPI: property: Introduce acpi_fwnode_name()
Date: Mon,  5 Nov 2018 12:17:25 +0300	[thread overview]
Message-ID: <20181105091727.25544-3-heikki.krogerus@linux.intel.com> (raw)
In-Reply-To: <20181105091727.25544-1-heikki.krogerus@linux.intel.com>

ACPI data nodes have a name, so let's return that when
fwnode_name() is called.
