Merge branch 'depends/tty-omap-serial' into next/cleanup
This part of the tty tree (unfortunately with all the preceding patches as well) is a dependency for some of the OMAP cleanups, so we've pulled it in as a dependency based on agreement with Greg. Signed-off-by: Olof Johansson <olof@lixom.net>
