commit 8014246694bb8bc6e09ceacdf00492a490a8cb08
category: bugfix
bugzilla: https://gitee.com/openeuler/kernel/issues/I5ZWFM

--------------------------------

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.
