Pull serial fixes from Greg KH:
 "Here are 3 tiny fixes that are needed for 3.12-final for some serial
  drivers.

  One of them is a revert of a broken patch, and two others are fixes
  for reported bugs.  All of these have been in linux-next for a while,
  I forgot I had not sent them to you yet, my fault"

(Actually, Greg, you _had_ sent two of the three, so this pulls in just
one actual new fix)
