    drivers/video/via/ioctl.c: prevent reading uninitialized stack memory, CVE-2010-4082
    
    CVE-2010-4082
    
    BugLink: http://bugs.launchpad.net/bugs/712744
    
    The VIAFB_GET_INFO device ioctl allows unprivileged users to read 246
    bytes of uninitialized stack memory, because the "reserved" member of
    the viafb_ioctl_info struct declared on the stack is not altered or
    zeroed before being copied back to the user.  This patch takes care of
    it.
