Ben, thanks for pointing out. I actually just tried to follow the
style of surrounding code, but happy to adjust if that's the preferred
option. From what I can see, these lines should still fit in below 80
cols even with increased indents...

Should we then also adjust other function calls within the driver with
similar indentation (if any), that are currently not touched by this
patch series?

Thanks,
Alexey
