[PATCH v2 4/4] drm/virtio: move virtio_gpu_mem_entry initialization to new function
Introduce new virtio_gpu_object_shmem_init() helper function which will
create the virtio_gpu_mem_entry array, containing the backing storage
information for the host. For the most path this just moves code from
virtio_gpu_object_attach().
