Hello,

I have a Tegra device that uses a stock android bootloader which passes "video=tegrafb" in
the kernels cmdline. That wasn't a problem before this patch, but now Tegra DRM driver
fails to probe because the mode is 0x0:0 and hence framebuffer allocation fails. Is it a
legit regression that should be fixed in upstream?
