    M controller/binding.c

  Log Message:
  -----------
  binding: Fix potential NULL dereference of lbinding.

There is a valid code path that can lead to 'lbinding' being NULL in
handle_deleted_vif_lport().  Make sure we check for it.

Found by code inspection.

Fixes: 68cf9fdceba8 ("binding: Fix container port removal from local bindings.")
