As people start replying to different patches, they are going to scatter-bomb throughout all of the recipient's inboxes. If/when you send a subsequent version, could you please ensure you send the set threaded so the patches keep in relation to one another as they are reviewed? -- Lee Jones [李琼斯] Linaro Services Technical Lead Linaro.org │ Open source software for ARM SoCs Follow Linaro: Facebook | Twitter | Blog -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
