 "Here are four small tty/serial driver fixes for 5.15-rc3. They
  include:

   - remove an export now that no one is using it anymore

   - mvebu-uart tx_empty callback fix

   - 8250_omap bugfix

   - synclink_gt build fix

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