From: Jeffrey Hugo <jeffrey.l.hugo@xxxxxxxxx> [ Upstream commit 9ca7ad6c7706edeae331c1632d0c63897418ebad ] add_gpu_components() adds found GPU nodes from the DT to the match list, regardless of the status of the nodes. This is a problem, because if the nodes are disabled, they should not be on the match list because they will not be matched. This prevents display from initing if a GPU node is defined, but it's status is disabled. Fix this by checking the node's status before adding it to the match list.
