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@jannau> 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.
