  tty: serial: fix help message for SERIAL_CPM (2025-09-17 13:11:30 +0200)

----------------------------------------------------------------
TTY/Serial update for 6.18-rc1

Here are some small updates for tty/serial drivers for 6.18-rc1.

Not many changes overall, just the usual:
  - abi cleanups and reworking of the tty functions by Jiri by adding
    console lock guard logic
  - 8250_platform driver updates
  - qcom-geni driver updates
  - other minor serial driver updates
  - some more vt escape codes added

All of these have been in linux-next for a while with no reported
issues.
