This is a well-structured v12 series adding Rust abstractions for the serial device bus (serdev). The design closely follows established Rust-for-Linux bus driver patterns (platform, USB, auxiliary). The probe/remove lifecycle is carefully handled with a `ScopeGuard` for cleanup on probe failure, and a `Mutex<bool>` (`active`) to protect against `receive_buf_callback` racing with either a failed probe or a drop. The series depends on Danilo Krummrich's driver-lifetime patches.

The code is generally clean and the safety comments are well-written. I found a few documentation typos, one questionable silent-overflow-to-infinite-timeout semantic, and a theoretical truncation issue in `write_all()`. None of these are showstoppers.

**Verdict:** Looks good with minor nits. The core abstraction design is sound.
