Having a callback invoked after registering to a subsystem (which used to be the case for devlink before the changes) is _normal_. You keep talking about .probe() like it's some magic period of complete quiescence. > Drivers that have implemented ops.flash_update() have no idea about that. I bet. I don't think this discussion is going anywhere, count me out.
