WARNING: possible circular locking dependency detected
------------------------------------------------------
kworker/u8:1/12 is trying to acquire lock:

but task is already holding lock:
ffff8880790c0768 (&rdev->wiphy.mtx){+.+.}-{4:4}, at: class_wiphy_constructor include/net/cfg80211.h:6061 [inline]
ffff8880790c0768 (&rdev->wiphy.mtx){+.+.}-{4:4}, at: ieee80211_remove_interfaces+0xf1/0x720 net/mac80211/iface.c:2280

which lock already depends on the new lock.

the existing dependency chain (in reverse order) is:
