I suspected so. But this is the only reason why changed the name. =)

If we don't change the name then the platform device will be attached
to the platform driver as usual, but the old platform data structure
will use a different binary format compated to what the driver
expects.

Changing the driver name makes sure that the old device disappears and
that people can move over to the new name and at the same time update
the platform data to the new format.

Thanks.

I can post an updated version where I keep the driver name unchanged
if you prefer that. But I'm pretty sure out-of-tree drivers will break
with NULL pointer accesses or similar if we update the platform data
format without changing the name. I don't think you want that. =)

Cheers,
