Devin,

As you didn't send your pull request in time for 3.6, I'll add this one,
as otherwise it will miss the 3.6 bus. 

You don't need to rebase your pull request due to that anyway, as, if a
merge conflict happens, I'll fix it, as it should be trivial.

I'm fixing trivial merge conflicts like that all the time. Just today, I
fixed maybe dozens of similar ones.

The conflicts that I ask developers to rework are the ones where the complex
logic is modified by two different patches.

On Ben's patchset, firmwares were added to the bridge driver. That's wrong.

Adding it to the driver that actually uses the firmware looks OK on my eyes.
