Subject: [PATCH 4.9 007/101] ARM: crypto: comment out gcc warning that breaks clang builds

From: Greg Kroah-Hartman <gregkh@...uxfoundation.org>

The gcc build warning prevents all clang-built kernels from working
properly, so comment it out to fix the build.

This is a -stable kernel only patch for now, it will be resolved
differently in mainline releases in the future.
