Merge tag 'tty-4.10-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/tty
Pull tty/serial updates from Greg KH:
"Here's the tty/serial patchset for 4.10-rc1.
It's been a quiet kernel cycle for this subsystem, just a small number
of changes. A few new serial drivers, and some cleanups to the old
vgacon logic, and other minor serial driver changes as well.
All of these have been in linux-next for a while with no reported
issues"
