Hi!

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:

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.

Dmitry Osipenko (2):
  of_graph: add of_graph_is_present()
  drm/of: Make drm_of_find_panel_or_bridge() to check graph's presence
