hwc-drm errors in logcat
My logcat dump on db820c is filled with following hwc-drm error messages post commit 34b954a8b506 ("drm_hwcomposer: Propagate PlanStage error"), specially if I open and browse thru Settings Application.

The errors seem to be non-fatal and I don't see any obvious graphics related issues either. Is there anything I should be worried about? Something missing from platform (db820c/db410c) implementation point of view? And if these errors are not so critical, then I'm curious if should we silence these messages instead?
