I took another look at this kind of corner cases. Timer is not disabled explicitely. But ongoing scan request is explicitely aborted in relevant cfg80211 ops, e.g. on virtual interface change or removal. Though it looks like some of AP usecases are not handled: e.g. when AP is stopped while scan is in progress. I will queue the fix into the next cleanup/bugfix patch series if it is needed to abort scan in such a case. Thanks, Sergey
