We cannot reference priv->fbdev outside of the #ifdef:

As the #ifdef is a bit annoying here, this removes it entirely and uses an IS_ENABLED() check in it place where needed.

I guess I wasn't clear enough, but you don't even need the IS_ENABLED. The cma_fini/init functions themselves don't get no-opped out (I guess we could fix that), but the underlying fb helper functions they call do, so this is all perfectly fine to call unconditionally. And that's what all other drivers do. Should I edit while applying, or do you want to respin?
Thanks, Daniel
