Cover letter [PATCH 0/8] serdev: receive_buf and locking fixes
This series addresses a few issues with the serdev code, including potential information leaks due to missing sanity checks in the receive path, a NULL-deref in write_wakeup() due to missing reference handling, and missing tty locking in close().
