Maximilian Luz 31d61c42f1 HID: surface-hid: Use correct event registry for managing HID events ... commit dc0fd0acb6 upstream. Until now, we have only ever seen the REG-category registry being used on devices addressed with target ID 2. In fact, we have only ever seen Surface Aggregator Module (SAM) HID devices with target ID 2. For those devices, the registry also has to be addressed with target ID 2. Some devices, like the new Surface Laptop Studio, however, address their HID devices on target ID 1. As a result of this, any target ID 2 commands time out. This includes event management commands addressed to the target ID 2 REG-category registry. For these devices, the registry has to be addressed via target ID 1 instead. We therefore assume that the target ID of the registry to be used depends on the target ID of the respective device. Implement this accordingly. Note that we currently allow the surface HID driver to only load against devices with target ID 2, so these timeouts are not happening (yet). This is just a preparation step before we allow the driver to load against all target IDs.
