    Hi,

    This is the friendly patch-bot of Greg Kroah-Hartman. You have sent him
    a patch that has triggered this response. He used to manually respond
    to these common problems, but in order to save his sanity (he kept
    writing the same thing over and over, yet to different people), I was
    created. Hopefully you will not take offence and will fix the problem
    in your patch and resubmit it so that it can be accepted into the Linux
    kernel tree.

    You are receiving this message because of the following common error(s)
    as indicated below:

    - Your patch did many different things all at once, making it difficult
    to review. All Linux kernel patches need to only do one thing at a
    time. If you need to do multiple things (such as clean up all coding
    style issues in a file/driver), do it in a sequence of patches, each
    one doing only one thing. This will make it easier to review the
    patches to ensure that they are correct, and to help alleviate any
    merge issues that larger patches can cause.

    - You did not specify a description of why the patch is needed, or
    possibly, any description at all, in the email body. Please read the
    section entitled "The canonical patch format" in the kernel file,
    Documentation/SubmittingPatches for what is needed in order to
    properly describe the change.

    - You did not write a descriptive Subject: for the patch, allowing Greg,
    and everyone else, to know what this patch is all about. Please read
    the section entitled "The canonical patch format" in the kernel file,
    Documentation/SubmittingPatches for what a proper Subject: line should
    look like.

    If you wish to discuss this problem further, or you have questions about
    how to resolve this issue, please feel free to respond to this email and
    Greg will reply once he has dug out from the pending patches received
    from other developers.

    thanks,

    greg k-h's patch email bot
