--------------------------------------------
syz.2.687/5873 is trying to acquire lock:
ffff0000ca834d00 (team->team_lock_key#4){+.+.}-{3:3}, at: team_port_change_check+0x5c/0x230 drivers/net/team/team.c:3004

but task is already holding lock:
ffff0000ca834d00 (team->team_lock_key#4){+.+.}-{3:3}, at: team_add_slave+0xa8/0x1fb0 drivers/net/team/team.c:1981

other info that might help us debug this:
 Possible unsafe locking scenario:

       CPU0
       ----
  lock(team->team_lock_key#4);
  lock(team->team_lock_key#4);

 *** DEADLOCK ***

 May be due to missing lock nesting notation
