Removal is correct. After patch 1, `TyrData`'s fields all auto-derive `Send`/`Sync`: `ARef<platform::Device>` is `Send`+`Sync`, `Mutex<Clocks>` is `Send`+`Sync` (where `Clocks` contains `Clk` and `OptionalClk`, now both `Send`+`Sync`), `Mutex<Regulators>` is `Send`+`Sync` (where `Regulator<T>` already has `Send`+`Sync` per commit 9a200cbdb543), and `GpuInfo` wraps a plain data struct. The commit message correctly explains that the `Regulator` case was already resolved in mainline.

No issues found.
