[PATCH tip/core/rcu 3/7] smsc: Replace spin_is_locked() with lockdep

[Paul E. McKenney]

From: Lance Roy <ldr709@xxxxxxxxx>

lockdep_assert_held() is better suited to checking locking requirements,
since it only checks if the current thread holds the lock regardless of
whether someone else does. This is also a step towards possibly removing
spin_is_locked().
