This small series improves DRM bridges code by silencing a noisy error coming from of-graph code for the device-trees that are missing a display bridge graph. graph: no port node found in ... One example where this error happens is an older bridge-less DTB used in conjunction with a newer kernel which has a display controller driver that supports DRM bridges. Changelog: v10:- Corrected doc-comment, unbroke the of_graph_get_next_endpoint() and improved commit's message in the "add of_graph_is_present()" patch. Thanks to Laurent Pinchart for spotting the problems! v9: - These two patches are factored out from [1] in order to ease applying of the patches. - The of_graph_presents() is renamed to of_graph_is_present() like it was requested by Rob Herring in the review comment to [1]. - Added Rob's r-b.
