Actually, thinking about this a little more, my patch actually does select only relevant devices, and not *all* platform devices. In my patch, the device power domain pointers are only added for devices where a clk_get() actually succeeds. In the original version, the runtime PM hooks are overridden for *all* platform devices, but ones that have no clock (or where clk_get() failed) have the additional overhead of still calling the custom PM ops, but the custom ops have nothing to do.
