So I used this series and removed the i2c_device_id table from the device driver. The driver could match correctly using the of_device_id table and also the module was auto-loaded when using my mentioned RFC patch to report OF style module aliases instead of always using the legacy one. I've also reviewed the patches and the changes looks good to me. I hope the patches can finally land since have been in the list for almost 2 years [0].
