Subject[PATCH 2/4] video: of: display_timing: Don't yell if no timing node is present
Date
There may be cases (like in panel-simple.c) where we have a sane
fallback if no timings are specified in the device tree. Let's get
rid of the unconditional pr_err(). We can add error messages in
individual drivers if it makes sense.

NOTE: we'll still print errors if the node is present but there are
problems parsing the timings.

Fixes: b8a2948fa2b3 ("drm/panel: simple: Add ability to override typical timing")
