Commit a9fa852886fd ("drm/exynos: dp: add of_graph dt binding support
for panel") made the Exynos DP DT binding more consistent since the OF
graph could be used to lookup either a panel or a bridge device node.
Before that commit, a panel would be looked up using a phandle and a
bridge using the OF graph which made the DT binding not consistent.
But the patch broke the later case since not finding a panel dev node
would cause the driver's to do a probe deferral instead of attempting
to lookup a bridge device node associated with the remote endpoint.
So instead of returning a -EPROBE_DEFER if a panel is not found, check
if there's a bridge and only do a probe deferral if both aren't found.

Any comments about this patch? It is needed to have display working on
machines with a bridge chip again so it should be pushed to -rc ASAP.
Please check v4.5-rc3, this patch is already merged there.
Best regards
