  serial: Clear UPF_DEAD before calling tty_port_register_device_attr_serdev() (2024-05-10 11:49:23 +0100)

----------------------------------------------------------------
TTY/Serial changes for 6.10-rc1

Here is the big set of tty/serial driver changes for 6.10-rc1.  Included
in here are:
  - Usual good set of api cleanups and evolution by Jiri Slaby to make
    the serial interfaces move out of the 1990's by using kfifos instead
    of hand-rolling their own logic.
  - 8250_exar driver updates
  - max3100 driver updates
  - sc16is7xx driver updates
  - exar driver updates
  - sh-sci driver updates
  - tty ldisc api addition to help refuse bindings
  - other smaller serial driver updates

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