    Linus Torvalds authored
    Pull tty / serial driver updates from Greg KH:
     "Here is the "large" TTY and Serial driver update for 5.3-rc1.
    
      It's in the negative number of lines overall as we removed an obsolete
      serial driver that was causing problems for some people who were
      trying to clean up some apis (the mpsc.c driver, which only worked for
      some pre-production hardware that no one has anymore.)
    
      Other than that, lots of tiny changes, cleaning up small things along
      with some platform-specific serial driver updates.
    
      All of these have been in linux-next for a while now with no reported
      issues"
