This was introduced (or well, left behind) by commit
eeca9fce1d71a4955855ceb0c3b13c1eb9db27c1 ('cfg80211: Schedule timeout
for all CRDA calls'). It could be useful to mention that commit in the
commit message since the resulting code from this new patch looks pretty
strange and that triggered me to take a closer look at what happened
here (looked like this is fine now).

That assignment of 'treatment' is now write-only and you might as well
remove that while cleaning this up. This being the only caller of
reg_process_hint_user(), even more cleanup could be done by removing
return value from there, but I'm not sure whether that would be of
sufficient benefit.
