Subject: [PATCH 1/8] fs/openpromfs: use full_name instead of path_component_name
Date: Wed,  7 Nov 2018 16:31:44 -0600	[thread overview]
Message-ID: <20181107223151.14991-2-robh@kernel.org> (raw)
In-Reply-To: <20181107223151.14991-1-robh@kernel.org>

In preparation to remove struct device_node.path_component_name, use
full_name instead. kbasename is used so full_name can be used whether it
is the full path or just the node's name and unit-address.
