[patch 3/5] Hotplug firmware loader for Keyspan usb-serial driver

[Jan Harkes]

Simple program to convert the keyspan firmware header files to IHEX
formatted files that can be loaded with hotplug.

This is really only needed once to convert the existing keyspan firmware
headers, which is what the next patch does.
