drm/amdgpu: temporarily disable broken Clang builds due to blown stac…
…k-frame commit 6f6cb17 upstream. Patch series "Fix a bunch of allmodconfig errors", v2. Since b339ec9 ("kbuild: Only default to -Werror if COMPILE_TEST") WERROR now defaults to COMPILE_TEST meaning that it's enabled for allmodconfig builds. This leads to some interesting build failures when using Clang, each resolved in this set. With this set applied, I am able to obtain a successful allmodconfig Arm build. This patch (of 2): calculate_bandwidth() is presently broken on all !(X86_64 || SPARC64 || ARM64) architectures built with Clang (all released versions), whereby the stack frame gets blown up to well over 5k. This would cause an immediate kernel panic on most architectures. We'll revert this when the following bug report has been resolved: llvm/llvm-project#41896.
