Note that SET_REPORT is synchronous, just like GET_REPORT, even though it does not provide any data back besides an error code. If a transport layer does SET_REPORT asynchronously, they can just ACK it immediately by writing an uhid_set_report_reply to uhid. This patch re-uses the synchronous uhid-report infrastructure to query user-space. Note that this means you cannot run SET_REPORT and GET_REPORT in parallel. However, that has always been a restriction of HID and due to its blocking nature, this is just fine. Maybe some future transport layer supports parallel requests (very unlikely), however, until then lets not over-complicate things and avoid request-lookup-tables.
