console: fix up ARM screen_info reference
Separating the VGA console screen_info from the EFI one unfortunately caused a build failure for footbridge that I had never caught with randconfig builds: arch/arm/kernel/setup.c:932:27: error: static declaration of 'vgacon_screen_info' follows non-static declaration 932 | static struct screen_info vgacon_screen_info = { | ^~~~~~~~~~~~~~~~~~ In file included from arch/arm/kernel/setup.c:44: arch/arm/include/asm/setup.h:40:27: note: previous declaration of 'vgacon_screen_info' with type 'struct screen_info' 40 | extern struct screen_info vgacon_screen_info; | ^~~~~~~~~~~~~~~~~~ arm-linux-gnueabi-ld: drivers/video/console/dummycon.o: in function `dummycon_init': dummycon.c:(.text+0xe4): undefined reference to `screen_info' Make sure the variable is global to avoid the conflict with the extern declaration, and make it work in dummycon.c Signed-off-by: Arnd Bergmann <arnd@arndb.de> Link: https://lore.kernel.org/r/20231017093947.3627976-2-arnd@kernel.org Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
