Unfortunately my channel switch announcement patches contained locking issues which I didn't notice during my test due to bad configuration. Johannes pointed them out, so here is my attempt to fix them. This series attempts to fix two issues: * There are "suspicious rcu_dereference_protected() usage" problems for ieee80211_assign_beacon and ieee80211_ibss_csa_beacon because the respective locking was missing * There is a circular dependency between the wdev/sdata-lock and the csa_finalize worker lock (see description in patch 3). These patches contain changes for issues in the RFC series pointed out by Johannes. I've also found another possible leak so I added this to the series. Patches are based on mac80211-next.
