More description would be nice. I don't think I get it.

I'm not convinced this should a channel thing here?

that variable name is ... highly unusual. please make it match its
surroundings better.

Ok so in struct wiphy, to me means that the *driver* said it was 40MHz
intolerant? That makes no sense, why would the driver want to say that
*statically*? I can see maybe dynamically, but statically?

not really necessary, but I guess it's ok.

I don't get this. All you use this variable for is setting a
variable ... that the driver could already have set. Seems completely
pointless.
