Merge tag 'staging-4.1-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging

Pull staging driver updates from Greg KH:
 "Here's the big staging driver patchset for 4.1-rc1.

  There's a lot of patches here, the Outreachy application period
  happened during this development cycle, so that means that there was a
  lot of cleanup patches accepted.  Other than the normal coding style
  and sparse fixes here, there are some driver updates and work toward
  making some of the drivers into "mergable" shape (like the Unisys
  drivers.)

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

+The node for this driver must be a child node of a SPI controller, hence
+all mandatory properties described in
+
+        Documentation/devicetree/bindings/spi/spi-bus.txt
+
+must be specified.
+
+Required properties:
+	- compatible:  	Must be one of the following, depending on the
+			model:
+				"mcp3001"
+				"mcp3002"
+				"mcp3004"
+				"mcp3008"
+				"mcp3201"
+				"mcp3202"
+				"mcp3204"
+				"mcp3208"
+
+
+Examples:
+spi_controller {
+	mcp3x0x@0 {
+		compatible = "mcp3002";
+		reg = <0>;
+		spi-max-frequency = <1000000>;
