Can't you just send from the correct address? ;p

How about the following to avoid negative options:

config DEV_COREDUMP
       bool "Enable device coredump" if EXPERT
       default y if WANT_DEV_COREDUMP
       help
         Enable the device coredump mechanism for drivers wanting to
         use it. Disabling allows for more sensitive systems or systems that
         don't want to ever access the information to not have the code,
         nor keep any data.

         If unsure, say Y.
