#     Merge tag 'tty-5.18-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/tty
#     
#     Pull tty/serial driver updates from Greg KH:
#      "Here are the big set of tty and serial driver changes for 5.18-rc1.
#     
#       Nothing major, some more good cleanups from Jiri and 2 new serial
#       drivers. Highlights include:
#     
#        - termbits cleanups
#     
#        - export symbol cleanups and other core cleanups from Jiri Slaby
#     
#        - new sunplus and mvebu uart drivers (amazing that people are still
#          creating new uarts...)
#     
#        - samsung serial driver cleanups
#     
#        - ldisc 29 is now "reserved" for experimental/development line
#          disciplines
#     
#        - lots of other tiny fixes and cleanups to serial drivers and
#          bindings
#     
#       All of these have been in linux-next for a while with no reported
#       issues"
