P2-ihdad-device-refactor.patch was adding imports for modules that don't exist in the source tree (parser, digital, dispatch, FixupEngine, InputStream). The build was failing with: error[E0432]: unresolved import `super::parser` error[E0432]: unresolved import `super::digital` error[E0432]: unresolved import `super::dispatch` error[E0432]: unresolved import `super::FixupEngine` error[E0432]: unresolved import `super::InputStream` This patch was speculative work referencing modules that were never committed to the source. Without those modules, the patch breaks the build. The Red Bear base fork (local/sources/base) has the same device.rs as upstream (no patch needed), so removing this patch is safe. The other P2-ihdad-* patches (P2-ihdad-graceful-init, P2-ihdad-hda-stream) remain as they don't add missing imports.
