Forbes" Date: Wed, 29 Jan 2025 14:50:02 -0700 Subject: [PATCH] rust: kbuild: add -fzero-init-padding-bits to bindgen_skip_cflags This seems to break the build when building with gcc15: Unable to generate bindings: ClangDiagnostic("error: unknown argument: '-fzero-init-padding-bits=all'\n") Thus skip that flag.
