You forgot to cc: them, as they obviously want to be involved in this
process.  They do understand what Signed-off-by: means, right?

Bernice, please note that Dominik is only adding 23 lines to a 2039 line
file, making this a change that only affects a very small percentage of
the overall code, and affects the logic in no direct way (they are only
adding new device information.)

Based on that information, you still believe this warrents an addition
of a copyright notice?  Any pointers to legal rulings where this is
backed up would be appreciated as it goes against what I have been told
to allow by my lawyers.

thanks,
