commit 0cfc36ea51684b5932cd3951ded523777d807af2 upstream.
Commit 30e945861f3b ("serial: stm32: add support for break control") added another usage of the port lock, but was merged on the same day as c5d06662551c ("serial: stm32: Use port lock wrappers"), therefore the latter did not update this usage to use the port lock wrappers.
