Subject: [PATCH] drm/fbdev: Select FB_CORE dependency for fbdev on DMA and TTM
Select FB_CORE if GEM's DMA and TTM implementations support fbdev
emulation. Fixes linker errors about missing symbols from the fbdev
subsystem.
Also see [1] for a related SHMEM fix.
Fixes: dadd28d4142f ("drm/client: Add client-lib module")
