Subject: checkpatch: possible modifiers are not being correctly matched
X-Git-Tag: v2.6.27-rc1~700

checkpatch: possible modifiers are not being correctly matched

Although we are finding the added modifier in the declaration below
we are not correctly matching it as a type.  Fix the declaration.

    static void __ref *vmem_alloc_pages(unsigned int order)
    {
    }
