While this change seems to be worthy on its own, the underlying issue
with Gen1 Hyper-V VMs won't be resolved without 

commit 2a8a8afba0c3053d0ea8686182f6b2104293037e

    Drivers: hv: Always reserve framebuffer region for Gen1 VMs

as 'fb_mmio' is still going to be unset in some cases without it.
