    Ohad's message to which you replied had:

    Cc: Ohad Ben-Cohen <>, Hari Kanigeri <>,
    Benoit Cousson <>, Tony Lindgren <>,
    Greg KH <>, Grant Likely <>,, Suman Anna <>

    Yours has:

    To: Ohad Ben-Cohen <>
    Cc: Hari Kanigeri <>, Benoit Cousson <>,
    Tony Lindgren <>, Greg KH <>,,
    Grant Likely <>,,, Suman Anna <>,

    which includes an invalid address "mattw@codeaurora.orgmattw". Is there
    a reason why you're excluding the linux-omap list from your message and
    subsequent discussion?
