As reported by Sam Ravnborg [1], after commit b8a2948fa2b3 ("drm/panel: simple: Add ability to override typical timing") we now see a pointless error message printed on every boot for many systems. Let's fix that by adjusting who is responsible for printing error messages when of_get_display_timing() is used.
Most certainly we can bikeshed the topic about whether this is the right fix or we should instead add logic to panel_simple_probe() to avoid calling of_get_display_timing() in the case where there is no "panel-timing" sub-node. If there is consensus that I should move the fix to panel_simple_probe() I'm happy to spin this series. In that case we probably should _remove_ the extra prints that were already present in the other two callers of of_get_display_timing().
While at it, fix a missing of_node_put() found by code inspection.
NOTE: amba-clcd and panel-lvds were only compile-tested.
