Linus Torvalds 8a500fd093 TTY / Serial driver update for 7.2-rc1
Here is the big set of TTY and Serial driver updates for 7.2-rc1.
 Overall we end up removing more code than added, due to an obsolete
 synclink_gt driver being removed from the tree, always a nice thing to
 see happen.
 
 Other than that driver removal, major things included in here are:
   - max310x serial driver updates and fixes
   - 8250 driver updates and rework in places to make it more "modern"
   - dts file updates
   - serial driver core tweaks and updates
   - vt code cleanups
   - vc_screen crash fixes
   - other minor driver updates and cleanups
 
 All of these have been in linux-next for well over a week with no
 reported issues.
