Can you create a branch with all these patches applied and send it to Tony ?
Tony, Will you able to pull this and send it up to arm-soc ? Regards, Santosh -- To unsubscribe from this list: send the line "unsubscribe linux-omap" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
