Hi Oyvind,
Thanks for looking at this.
At this moment, I don't really see a benefit one way or anther, so
I am going to stick with the macro version for now, changing the one
remaining module_param_named() you mentioned to using the macros to
keep things consistent.
If one day we have a paramter with a long ORing of the macros, then
we can revisit this decision.
