Merge tag 'char-misc-3.11-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc
Pull char/misc updates from Greg KH:
"Here's the big char/misc driver tree merge for 3.11-rc1
A variety of different driver patches here. All of these have been in
linux-next for a while, and the networking patches were acked-by David
Miller, as it made sense for those patches to come through this tree"
* tag 'char-misc-3.11-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc: (102 commits)
