    Subject[PATCH 4.4 48/72] mei: remove dev_err message on an unsupported ioctl
    Date
    4.4-stable review patch.  If anyone has any objections, please let me know.

    ------------------

    From: Colin Ian King <colin.king@canonical.com>

    commit bb0829a741792b56c908d7745bc0b2b540293bcc upstream.

    Currently the driver spams the kernel log on unsupported ioctls which is
    unnecessary as the ioctl returns -ENOIOCTLCMD to indicate this anyway.
    I suspect this was originally for debugging purposes but it really is not
    required so remove it.
