I'm saying that more code is added in later patches around the 
devlink_register() for the health (patch 4) and parameters (patch 11). 
This allows me to have a simple line in the main probe logic that does 
the devlink-register related things, and then have the details collected 
together off to the side.

Obviously, when I update the code for using the devl_* interfaces and 
explicit locking, those two patches will change a little.
