TTY/Serial bugfixes for 3.16-rc2 

Here are some tty / serial driver bugfixes for 3.16-rc2 that resolve
 some reported issues.  The samsung driver build error itself has been
 reported by a bunch of people, sorry about that one.  The others are all
 tiny and everyone seems to like them in linux-next so far.
