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.

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.
