    Ohad's message to which you replied had:

    To: linux-omap@vger.kernel.org, linux-kernel@vger.kernel.org,
    linux-arm-kernel@lists.infradead.org
    Cc: Ohad Ben-Cohen <ohad@wizery.com>, Hari Kanigeri <h-kanigeri2@ti.com>,

    Yours has:

    mattw@codeaurora.orgmattw, linux-arm-kernel@lists.infradead.org

    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?
