Hi Marek, > This patch landed in today's (20210122) linux-next as commit > 791daf8fc49a ("cfg80211: avoid holding the RTNL when calling the > driver"). Sadly, it causes deadlock with mwifiex driver. I think that > lockdep report describes it enough: Yeah, umm, sorry about that. Evidently, I somehow managed to put "wiphy_lock()" into that part of the code, rather than "wiphy_unlock()"! I'll fix, thanks! johannes
