From af87b3d0151e39f23e795d327e25019be687d8c0 Mon Sep 17 00:00:00 2001 From: David Herrmann Date: Sat, 6 Apr 2013 20:28:51 +0200 Subject: Bluetooth: hidp: don't send boot-protocol messages as HID-reports If a device is registered as HID device, it is always in Report-Mode. Therefore, we must not send Boot-Protocol messages on hidinput_input_event() callbacks. This confuses devices and may cause disconnects on protocol errors. We disable the hidinput_input_event() callback for now. We can implement it properly later, but lets first fix the current code by disabling it.
