Subject: [PATCH] headers: fix lockdep_assert_not_held()
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
LOCK_STATE_HELD define was omitted during backport of
lockdep_assert_not_held() which leads to build failures of kernels with
CONFIG_LOCKDEP=y:
backports-5.15.8-1/backport-include/linux/lockdep.h:16:47: error: 'LOCK_STATE_HELD' undeclared (first use in this function)
Fix it by adding missing LOCK_STATE_HELD define.
