dma_buf may live a long time, longer than the last direct user of the driver. We already hold a reference to the owner module (that prevents the object code from disappearing), but there is no reference to the drm_dev - so the pointers to the driver backend themselves may vanish. v2: Resist temptation to fix the bug in armada_gem.c not setting the correct flags on the exported dma-buf (it should pass the flags through and not be arbitrarily setting O_RDWR). Use a common wrapper for exporting the dmabuf and acquiring the reference to the drm_device.
