    [PATCH] Correct case sensitivity in make mandocs · ab642d48
    Andrew Morton authored
    From: Michael Still <mikal@stillhq.com>
    
    The attached patch corrects case sensitivity in the mandocs make target.
    XML is case insensitive, and a bunch of the kernel-doc assumes this.  The
    makeman and splitman scripts incorrectly cared about case.  This patch also
    updates the Docbook DTD version which the script generates.
