Subject: [PATCH v10 0/2] Silence missing-graph error for DRM bridges
Date: Wed, 1 Jul 2020 10:42:30 +0300 [thread overview]
Message-ID: <20200701074232.13632-1-digetx@gmail.com> (raw)
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:
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.
