Merge tag 'char-misc-3.6' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc
Pull char/misc driver merge from Greg Kroah-Hartman: "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).
