4.9-stable review patch. If anyone has any objections, please let me know.
------------------ From: David Lin <[email protected]> commit bb3f38c3c5b759163e09b9152629cc789731de47 upstream. We should avoid using the space character when passing arguments to clang, because static code analysis check tool such as sparse may misinterpret the arguments followed by spaces as build targets hence cause the build to fail.
