Aren't you getting any warnings here about dropping the 'const' from
the global structure?
I tried a build with W=1 to check for warning I might have missed but
can't catch any here.
It's done in the exact same way in many other upstream drivers.
Anyway I can remove the const here if you think that could create
trouble at some point.
Just let me know your recommendation.
