Subject: [PATCH 4.14 008/229] 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.
