Actually it applies if the first patch of this v2 series is also applied first.
https://patchwork.kernel.org/patch/9458883/
https://patchwork.kernel.org/patch/9458889/
The 3rd patch of the series can be discarded though since it was just
an example to show the benefit of the first two.
I guess someone needs to also ack/review the first one. Because
switching to radix tree keeping the const qualifier of the driver
structure isn't really useful.
