Since __regmap_init() doesn't keep a persistent reference to the config,
just performs a deep copy of it (including regmap_set_name() ->
kstrdup_const()), technically you could have gotten away with just a
single on-stack regmap_config whose .name you kept changing for all 3
calls.

But this is perfectly valid as well.

I don't think you need to do anything further, just wait for Vinod to
start going through the backlog.
