Comment 44 for bug 1737750

With the attached patch nvidia-340.104 module may be build with both kernels linux-generic-hwe-16.04 4.15.0 and linux-generic 4.4.0

Tested on "VGA compatible controller: NVIDIA Corporation GT218 [GeForce 210] (rev a2) (prog-if 00 [VGA controller])" (GeForce 210 0x0A65)

It should fix nv_drm_init/exit issues
