Subject: [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().

  serdev: ttyport: add missing receive_buf sanity checks
