char/misc driver merge for 3.7-rc1

Browse source 
Here is the "big" char/misc driver tree update for the 3.7-rc1 merge
 window.
 
 Nothing major, just a number of driver updates and fixes, all of which
 have been in the linux-next releases for a while now either in my tree,
 or in Andrew's (the lis3l driver changes came from his tree last week).
