While playing with hid_bpf_hw_output_report() on a device without report IDs, I realized I wasn't able to send proper reports to the USB endpoint. This is because the __hid_bpf_hw_check_params() check wasn't taking into account the report ID reserved space, and it was trimming down one element in the report. [...]
