Mario Limonciello fc326d9ad4 trivial: synaptics-rmi: hardcode Vendor string 
Right now vendor string is detected by walking up the udev chain
until a vendor is found.  On some systems this is finding incorrect
data such as `Intel Corporation` for the vendor on the touchpad.

As the plugin only supports Synaptics devices, Correct it by hardcoding
vendor to `Synaptics`.

Sample output:
```

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

Vendor ID Security

The vendor ID is set from the udev vendor, in this instance set to HIDRAW:0x06CB

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
