klocalizer: localized config does not compile drivers/gpu/drm/i915/gvt/*.c

[necipfazil]

At linux-next commit b01739fb865a:

klocalizer -a x86_64 drivers/gpu/drm/i915/gvt/display.o
make olddefconfig; make clean drivers/gpu/drm/i915/gvt/display.o

Results in:

[...]

However, it can be compiled with allyesconfig:

make allyesconfig
make clean drivers/gpu/drm/i915/gvt/display.o

Some other files with the same issue are:

• drivers/gpu/drm/i915/gvt/gvt.c
• drivers/gpu/drm/i915/gvt/handlers.c
• drivers/gpu/drm/i915/gvt/vgpu.c

This bug is related to kmax.

klocalizer --view-kbuild -a x86_64 drivers/gpu/drm/i915/gvt/display.o

However, drivers/gpu/drm/i915/gvt/ depends on CONFIG_DRM_I915_GVT:
