[Arm-dev] HC1 - Kernel error reported by logwatch

On my Odroid HC1 running the 4.19 kernel, I see in the logwatch email:

--------------------- Kernel Begin ------------------------


  WARNING:  Kernel Errors Present
     WARNING: CPU(s) started in wrong/inconsistent mo ...:  3 Time(s)
     [drm:exynos_drm_bind [exynosdrm]] *ERROR* no device found ...: 3 
Time(s)

  ---------------------- Kernel End -------------------------


Greping in messages I found:

and

no device found for DMA mapping operations.

Anything to do about these?
