Description

In the Linux kernel, the following vulnerability has been resolved: bnxt_en: Fix lockdep warning during rmmod The commit under the Fixes tag added a netdev_assert_locked() in bnxt_free_ntp_fltrs(). The lock should be held during normal run-time but the assert will be triggered (see below) during bnxt_remove_one() which should not need the lock. The netdev is already unregistered by then. Fix it by calling netdev_assert_locked_or_invisible() which will not assert if the netdev is unregistered.
