    The SNDRV_HDSP_IOCTL_GET_CONFIG_INFO and
    SNDRV_HDSP_IOCTL_GET_CONFIG_INFO ioctls in hdspm.c and hdsp.c allow
    unprivileged users to read uninitialized kernel stack memory, because
    several fields of the hdsp{m}_config_info structs declared on the stack
    are not altered or zeroed before being copied back to the user.  This
    patch takes care of it.
