TTY/Serial driver fixes for 4.16-rc6

Browse source 
Here are some small TTY core and Serial driver fixes for 4.16-rc6.
 
 They resolve some newly reported bugs, as well as some very old ones,
 which is always nice to see.  There is also a new device id added in
 here for good measure.
 
 All of these have been in linux-next for a while with no reported
 issues.
