cfg80211: fix processing world regdomain when non modular
This allows processing of the last regulatory request when we determine its still pending. Without this if a regulatory request failed to get processed by userspace we wouldn't be able to re-process it later. An example situation that can lead to an unprocessed last_request is enabling cfg80211 to be built-in to the kernel, not enabling CFG80211_INTERNAL_REGDB and the CRDA binary not being available at the time the udev rule that kicks of CRDA triggers. In such a situation we want to let some cfg80211 triggers eventually kick CRDA for us again. Without this if the first cycle attempt to kick off CRDA failed we'd be stuck without the ability to change process any further regulatory domains. cfg80211 will trigger re-processing of the regulatory queue whenever schedule_work(&reg_work) is called, currently this happens when: * suspend / resume * disconnect * a beacon hint gets triggered (non DFS 5 GHz AP found) * a regulatory request gets added to the queue We don't have any specific opportunistic late boot triggers to address a late mount of where CRDA resides though, adding that should be done separately through another patch. Without an opportunistic fix then this fix relies at least one of the triggeres above to happen. Reported-by: Sander Eikelenboom <linux@eikelenboom.it> Signed-off-by: Luis R.
