I think this intermediately breaks the build, if you disable fbdev
support. That's now supported in the fbdev helpers core generically across
all drivers.

Not sure how to best fix this up, since the only way would be to squash
these patches, plus generic deferred io plus the conversion patches for
udl/qxl all into one. Tricky.
