Changing bq27200-0 to bq27200_0 is forbidden in -rc6 time. If you
believe noone depends on the name, argue your case, and it might be
possible to change it in -rc0.
If someone uses the name, they care about the device, and you can't
take it away.

If the use doesn't depend on the name, you may get away with changing
the name. (But not in -rc6.)

That is not useful argumentation.
