Hmm, this is likely caused by building with a Kconfig with FBDEV disabled.
The attached patch should fix this. I will send out a v5 with this squashed in
later
today.

Subject: [PATCH] staging/vboxvideo: Use various drm_fb_helper funcs instead of
DIY code
Besides being a nice cleanup, this fixes vobxvideo not building when
fbdev support is disabled in the Kconfig.
