First of all, we saw you patch.

yours has the same Subject as mine. This is not how we do patches.
Consult Documentation/SubmittingPatches about how to do them properly.

What is more, your patch doesn't have a commit message. But it needs one.

Fix all that, send it as a *separate* patch after mine has been applied
and people will take a look then.

If we're going to use the "efifb" prefix, change those to pr_info and
define pr_fmt - lotsa examples in the kernel sources.

More importantly, you'd need a consensus from people that the printks in
efifb are really not interesting and should be behind efi=debug.

HTH.
