Pull tty/serial fixes from Greg KH:
"Here are some small tty and serial driver fixes for 4.13-rc2. Nothing
huge at all, a revert of a patch that turned out to break things, a
fix up for a new tty ioctl we added in 4.13-rc1 to get the uapi
definition correct, and a few minor serial driver fixes for reported
issues.
All of these have been in linux-next for a while with no reported
issues"
