Richard Hughes 8523ebebf2 synaptics-rmi: Also add the product ID as a GUID without the minor version 
Firmware may be suitable for all products that match the 'major ID' and so we
should provide an extra GUID to use in this case.

Synaptics RMI4 Support

Introduction

This plugin updates integrated Synaptics RMI4 devices, typically touchpads.

GUID Generation

The HID DeviceInstanceId values are used, e.g. HIDRAW\VEN_06CB&DEV_4875.

These devices also use custom GUID values constructed using the board ID, e.g.

  • SYNAPTICS_RMI\TM3038-002
  • SYNAPTICS_RMI\TM3038

Firmware Format

The daemon will decompress the cabinet archive and extract a firmware blob in a proprietary (but docucumented) file format.

This plugin supports the following protocol ID:

  • com.synaptics.rmi
