Chris Wilson bdb821ca44 drm/i915: Enable swfence debugobject support for i915.ko
Only once the debugobject symbols are exported can we enable support for
debugging swfences when i915 is built as a module. Requires commit
2617fdca3f68 ("lib/debugobjects: export for use in modules")

Add -Werror to the build flags for (and only for) i915.ko.
Do not enable this unless you are writing code for the i915.ko module.
