A rebase of the asahi driver onto this series still probes the platform
device and the driver works as expected.

Feel free to add
Tested-by: Janne Grunau <j@...nau>

We plan to import this series for the Asahi Linux downstream kernel
starting with v6.12 and replace the old rust-for-linux Device/Driver
abstractions with this.
