Subject: [PATCH] drm/gpuvm: allow building as module
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Currently, the DRM GPUVM does not have any core dependencies preventing
a module build.
Also, new features from subsequent patches require helpers (namely
drm_exec) which can be built as module.
