The dell driver dose not use rely on udev in userspace, nor the
/lib/firmware path. It has its own userspace component, which just
happens to reuse some of the infrastructure the udev firmware helper
used to use. This has now been split up, and as of 3.17 the firmware
loader can safely be removed from udev.
