Hi Peter, We normally like to see new options turned on after the driver/option has been merged, so send this during or right after the merge window when that happens, please. I also see that this is statically enabling this driver -- we try to keep as many drivers as possible as modules to avoid the static kernel from growing too large. Would that be a suitable approach here, or is the driver needed to reach rootfs for further module loading? Thanks, -Olof
