Revision e31f6456c01c76f154e1b25cd54df97809a49edb authored by Amar Singhal on 20 July 2018, 19:15:18 UTC, committed by Johannes Berg on 24 July 2018, 07:11:31 UTC
Currently user regulatory hint is ignored if all wiphys in the system are self managed. But the hint is not ignored if there is no wiphy in the system. This affects the global regulatory setting. Global regulatory setting needs to be maintained so that it can be applied to a new wiphy entering the system. Therefore, do not ignore user regulatory setting even if all wiphys in the system are self managed.
