[ Upstream commit f1d4836201543e88ebe70237e67938168d5fab19 ]
GCC throws out this warning on arm64.
drivers/firmware/efi/libstub/arm-stub.c: In function 'efi_entry': drivers/firmware/efi/libstub/arm-stub.c:132:22: warning: variable 'si' set but not used [-Wunused-but-set-variable]
Fix it by making free_screen_info() a static inline function.
