Then someone could simply point me to the device tree file where that
"platform:" alias comes from. (Note that I, of course, do check the tree
for the substrings involved before tossing questions like these onto
lkml.)

Besides, as far as I can tell, for device tree support the magic
actually hides in
    MODULE_DEVICE_TABLE(of, rockchip_max98090_of_match);

Which, I think, implies that any MODULE_ALIAS("platform:[...]") is
pointless for systems booting with device tree support.

Thanks,


Paul Bolle
