I've also removed this.  The following is mostly for comment only.
I'm intending to commit this change by Monday at the latest.

[PATCH] Serial: remove unnecessary register_serial/unregister_serial

prototypes but don't use them.  FRV contains a commented out
call to register_serial.  Since these are deprecated, remove
these unnecessary references.
