I have dropped this patch and because it updates both driver documentation and shmobile code. Please split the patch into two, one to be taken by the driver maintainer, Mark Brown. And one to be taken by me. Thanks I have also dropped the second patch of this series, which depends on this patch. -- To unsubscribe from this list: send the line "unsubscribe linux-spi" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
