Date: Wed, 21 Nov 2007 15:03:55 -0800 From: akpm@...ux-foundation.org To: marcel@...tmann.org Cc: netdev@...r.kernel.org, akpm@...ux-foundation.org, hidave.darkstar@...il.com Subject: [patch 1/5] bluetooth: hidp_process_hid_control remove unnecessary parameter dealing From: Dave Young <hidave.darkstar@...il.com> 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.
