Merge tag 'tty-6.19-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/tty

Pull tty/serial updates from Greg KH:
 "Here is the big set of tty/serial driver changes for 6.19-rc1. Nothing
  major at all, just small constant churn to make the tty layer
  "cleaner" as well as serial driver updates and even a new test added!
  Included in here are:

   - More tty/serial cleanups from Jiri

   - tty tiocsti test added to hopefully ensure we don't regress in this
     area again

   - sc16is7xx driver updates

   - imx serial driver updates

   - 8250 driver updates

   - new hardware device ids added

   - other minor serial/tty driver cleanups and tweaks

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