stable inclusion from stable-v5.10.135 commit 8014246694bb8bc6e09ceacdf00492a490a8cb08 category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I5ZWFM
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=...
--------------------------------
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.
