I definitely don't have a problem cleaning this up in net-next. I wanted
a minimal patch for stable because I didn't check history where and when
additional users of dev_get_by_flags_rcu were removed.

`git grep` should show you we only have one caller. Apparently we don't
care about any out-of-tree module.

Point is : you did not check if some stable versions had more callers.

Its very nice you checked current version, but it is not enough for a
stable candidate.
