[PATCH] sparc: Fix undefined reference to fb_is_primary_device

[PATCH] sparc: Fix undefined reference to fb_is_primary_device

[Javier Martinez Canillas]

Commit 55bffc8170bb ("fbdev: Split frame buffer support in FB and FB_CORE
symbols") added a new FB_CORE Kconfig symbol, that can be enabled to only
have fbcon/VT and DRM fbdev emulation, but without support for any legacy
fbdev driver.

Unfortunately, it missed to change a CONFIG_FB in arch/sparc/Makefile and
that leads to the following linking error in some sparc64 configurations:

   sparc64-linux-ld: drivers/video/fbdev/core/fbcon.o: in function `fbcon_fb_registered':
>> fbcon.c:(.text+0x4f60): undefined reference to `fb_is_primary_device'

Fixes: 55bffc8170bb ("fbdev: Split frame buffer support in FB and FB_CORE symbols")
Reported-by: kernel test robot <lkp@intel.com>
Closes: https://lore.kernel.org/r/202401290306.IV8rhJ02-lkp@intel.com/
Signed-off-by: Javier Martinez Canillas <javierm@redhat.com>

I don't have a sparc64 toolchain to test this patch, but I'm pretty sure
that this is the correct fix for the linking error reported by the robot.

I think you also have to fix arch/sparc/Makefile.
