Merge tag 'staging-3.9-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging

Pull staging tree update from Greg Kroah-Hartman:
 "Here's the big staging tree merge for 3.9-rc1

  Lots of cleanups and updates for drivers all through the staging tree.
  We are pretty much "code neutral" here, adding just about as many
  lines as we removed.

  All of these have been in linux-next for a while."

+Description:
+		This is mounting matrix for motion sensors. Mounting matrix
+		is a 3x3 unitary matrix. A typical mounting matrix would look like
+		[0, 1, 0; 1, 0, 0; 0, 0, -1]. Using this information, it would be
+		easy to tell the relative positions among sensors as well as their
+		positions relative to the board that holds these sensors. Identity matrix
+		[1, 0, 0; 0, 1, 0; 0, 0, 1] means sensor chip and device are perfectly
+		aligned with each other. All axes are exactly the same.
