From eff001e35a857361f3fb289fea86e97c334a5446 Mon Sep 17 00:00:00 2001 From: Dave Young <hidave.darkstar@gmail.com> Date: Tue, 5 Feb 2008 03:07:14 -0800 Subject: bluetooth: hidp_process_hid_control remove unnecessary parameter dealing According to the bluetooth HID spec v1.0 chapter 7.4.2 "This code requests a major state change in a BT-HID device. A HID_CONTROL request does not generate a HANDSHAKE response." "A HID_CONTROL packet with a parameter of VIRTUAL_CABLE_UNPLUG is the only HID_CONTROL packet a device can send to a host. A host will ignore all other packets." So in the hidp_precess_hid_control function, we just need to deal with the UNLUG packet.
