I think we also need to update update ms_ff_worker() which assumes that
hid_hw_output_report() returns zero on success. Please use the Fixes
tag for this since a lot of scripts rely on it to decide what to
backport.
Fixes: 48d9cc9d85dd ("Bluetooth: hidp: Let hidp_send_message return number of queued bytes")
Otherwise, it looks good. Thanks for catching this.
regards,
dan carpenter
