  3. backend/drm: fail on explicit modifier in drmModeAddFB2 

    drmModeAddFB2 doesn't support explicit modifiers. Only accept INVALID
which indicates an implicit modifier and LINEAR which may indicate
that GBM_BO_USE_LINEAR has been used.

  5. render/drm_format_set: remove special LINEAR case 

    This was used to make the intersection of INVALID and LINEAR result
in LINEAR. We can now just require LINEAR to be in both lists.
