Subject: linux-next: build failure due to the drm tree

Hi all,

Today's -next fails to build an arm64 allnoconfig:

aarch64-none-linux-gnu-ld: drivers/firmware/sysfb.o: in function `sysfb_init':
sysfb.c:(.init.text+0xc): undefined reference to `screen_info'
aarch64-none-linux-gnu-ld: drivers/firmware/sysfb.o: relocation R_AARCH64_ADR_PREL_PG_HI21 against symbol `screen_info' which may bind externally can not be used when making a shared object; recompile with -fPIC
sysfb.c:(.init.text+0xc): dangerous relocation: unsupported relocation
aarch64-none-linux-gnu-ld: sysfb.c:(.init.text+0x10): undefined reference to `screen_info'
make[1]: *** [/tmp/next/build/Makefile:1276: vmlinux] Error 1

Caused by

d391c58271072d0b0f ("drivers/firmware: move x86 Generic System Framebuffers support")

or one of the related commits.

Yes, this was already reported by the kernel test robot and posted a fix
a few days ago: https://lore.kernel.org/patchwork/patch/1465623/
