It's a form letter :) The amount of patches I deal with precludes me from providing custom responses to all patches, especially when the real reason here was that the patch, as-is, didn't apply.

So far I believed MODULE_DEVICE_TABLE is used for "modinfo" only. I also believed that loading module is triggered by the "id_table".
