Hi,

My trusty R7525 test box is failing to show a console, or in fact anything,
on current -git. There's no output after:

Loading Linux 6.7.0+ ...
Loading initial ramdisk ...

and I don't get a console up. I went through the bisection pain and
found this was the culprit:

commit df67699c9cb0ceb70f6cc60630ca938c06773eda
Author: Thomas Zimmermann <tzimmermann@suse.de>

firmware/sysfb: Clear screen_info state after consuming it

Reverting this commit, and everything is fine. Looking at dmesg with a
buggy kernel, I get no frame or fb messages. On a good kernel, it looks
ilke this:

[ 1.416486] efifb: probing for efifb
[ 1.416602] efifb: framebuffer at 0xde000000, using 3072k, total 3072k
[ 1.416605] efifb: mode is 1024x768x32, linelength=4096, pages=1
[ 1.416607] efifb: scrolling: redraw
[ 1.416608] efifb: Truecolor: size=8:8:8:8, shift=24:16:8:0
[ 1.449746] fb0: EFI VGA frame buffer device

Happy to test a fix, or barring that, can someone just revert this
commit please?
