The header file <linux/efi.h> does not need anything from
<linux/screen_info.h>. Declare struct screen_info and remove
the include statements. Update a number of source files that
require struct screen_info's definition.

Hi, Thomas


I love your patch, LoongArch also have UEFI GOP support,

Maybe the arch/loongarch/kernel/efi.c don't include the '#include 
<linux/screen_info.h>' explicitly.

Oh, thank you for testing. I try to build arch/ changes on all of the 
affected platforms, but I cannot build for all of them. I have no means 
of building for loongarch ATM.

I'll update the patch according to your feedback.

Best regards
Thomas
