other info that might help us debug this:

Chain exists of:
  &sb->s_type->i_mutex_key#23 --> gadget_subsys.su_mutex --> &opts->dep_lock

 Possible unsafe locking scenario:

other info that might help us debug this:

Chain exists of:
  &sb->s_type->i_mutex_key#23 --> gadget_subsys.su_mutex --> &opts->dep_lock

 Possible unsafe locking scenario:

       CPU0                    CPU1
       ----                    ----
  lock(&opts->dep_lock);
                               lock(gadget_subsys.su_mutex);
                               lock(&opts->dep_lock);
  lock(&sb->s_type->i_mutex_key#23);
