URL: https://github.com/llvm/llvm-project/commit/38832a8443d76ce96b7e893a80538b9c3515a22a DIFF: https://github.com/llvm/llvm-project/commit/38832a8443d76ce96b7e893a80538b9c3515a22a.diff LOG: [clang] fix obtaining EnumDecl for UsingEnumDecl (#156127) Use the castAs acessor for the type for a UsingEnumDecl, as it can be sugar for an EnumType. Fixes a regression reported here: https://github.com/llvm/llvm-project/pull/155313#issuecomment-3238482327 Since this regression was never released, there are no release notes.
