This looks to be the wrong approach, and I think a patch has got
dropped somewhere.

On our Raspberry Pi downstream vendor tree we have a patch [1] from
Eric that renames v3d_v3d_pm_ops to v3d_pm_ops (don't need the
duplicated suffix), and adds it to v3d_platform_driver. Why that never
made it through the mainline trees I don't know.

Eric: How good's your memory on this one?

Thanks
