Change Bluetooth HID Profile Name (1/11)
Make the Bluetooth HID profile name consistent with the Bluetooth HID service name. BluetoothInputHost → BluetoothHidDevice BluetoothInputDevice → BluetoothHidHost IBluetoothInputHost → IBluetoothHidDevice IBluetoothInputDevice → IBluetoothHidHost BluetoothProfile.INPUT_HOST → BluetoothProfile.HID_DEVICE BluetoothProfile.INPUT_DEVICE → BluetoothProfile.HID_HOST Bug: 68055651 Test: make Change-Id: Iadb890a54dd3d6868b87514472bbac6bb0c6179f
