#     Merge tag 'tty-5.5-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/tty
#     
#     Pull tty/serial updates from Greg KH:
#      "Here is the "big" tty and serial driver patches for 5.5-rc1.
#     
#       It's a bit later in the merge window than normal as I wanted to make
#       sure some last-minute patches applied to it were all sane. They seem
#       to be :)
#     
#       There's a lot of little stuff in here, for the tty core, and for lots
#       of serial drivers:
#     
#        - reverts of uartlite serial driver patches that were wrong
#     
#        - msm-serial driver fixes
#     
#        - serial core updates and fixes
#     
#        - tty core fixes
#     
#        - serial driver dma mapping api changes
#     
#        - lots of other tiny fixes and updates for serial drivers
#     
#       All of these have been in linux-next for a while with no reported
#       issues"
