Patches 1-3 applied. Patch 4 has checkpatch has checkpatch warnings:

	WARNING: DT compatible string "st,m24c08" appears un-documented -- check ./Documentation/devicetree/bindings/
	#255: FILE: arch/arm/boot/dts/nvidia/tegra30-lg-x3.dtsi:1243:
	+			compatible = "st,m24c08", "atmel,24c08";

So I've left it out for now.
