   9 LOCK_STATE_HELD define was omitted during backport of
  10 lockdep_assert_not_held() which leads to build failures of kernels with
  11 CONFIG_LOCKDEP=y:
  12
  13  backports-5.15.8-1/backport-include/linux/lockdep.h:16:47: error: 'LOCK_STATE_HELD' undeclared (first use in this function)
  14
  15 Fix it by adding missing LOCK_STATE_HELD define.
