Arnd Bergmann adaeb718d4 vfio/gvt: fix DRM_I915_GVT dependency on VFIO_MDEV ... The Kconfig dependency is incomplete since DRM_I915_GVT is a 'bool' symbol that depends on the 'tristate' VFIO_MDEV. This allows a configuration with VFIO_MDEV=m, DRM_I915_GVT=y and DRM_I915=y that causes a link failure: x86_64-linux-ld: drivers/gpu/drm/i915/gvt/gvt.o: in function `available_instances_show': gvt.c:(.text+0x67a): undefined reference to `mtype_get_parent_dev' x86_64-linux-ld: gvt.c:(.text+0x6a5): undefined reference to `mtype_get_type_group_id' x86_64-linux-ld: drivers/gpu/drm/i915/gvt/gvt.o: in function `description_show': gvt.c:(.text+0x76e): undefined reference to `mtype_get_parent_dev' x86_64-linux-ld: gvt.c:(.text+0x799): undefined reference to `mtype_get_type_group_id' Clarify the dependency by specifically disallowing the broken configuration. If VFIO_MDEV is built-in, it will work, but if VFIO_MDEV=m, the i915 driver cannot be built-in here.
