Right. Patch 5 selects DRM_CLIENT in the driver's Kconfig item. This
will prove the plain drm_client code without any of the shared
implementations (fbdev, log, etc). Unless the user enabled such an
implementation, of course.
I've tried several combinations of =y and =m settings of these options
and found this to be working well.
Best regards
