[PATCH 04/16] i40e: Replace spin_is_locked() with lockdep

From: Lance Roy
Date: Wed Oct 03 2018 - 01:39:58 EST


lockdep_assert_held() is better suited to checking locking requirements,
since it won't get confused when someone else holds the lock. This is
also a step towards possibly removing spin_is_locked().
