So just looking at this patch, what's the *advantage* to the driver writer?

Apart from the actual new feature, this patch seems to actively make
the driver uglier.

I mentioned this before, but replacing "request_firmware()" with
"driver_data_request_simple()" is SIMPLY NOT AN IMPROVEMENT.

The new name is longer and _less_ descriptive.

So I'm really not seeing why you want to make these conversions that
just make code worse.
