4.9-stable review patch. If anyone has any objections, please let me know.
------------------ From: Mauro Carvalho Chehab <[email protected]> commit e2a91f4f42018994d7424d405900d17eba6555d0 upstream. PDF build on Kernel 4.9-rc? returns an error with Sphinx 1.3.x and Sphinx 1.4.x, when trying to solve some cross-references. The solution is to redefine the \DURole macro. However, this is redefined too late. Move such redefinition to LaTeX preamble and bind it to just the Sphinx versions where the error is known to be present.
