Make these const as they are only used in a copy operation. Done using Coccinelle:

@match disable optional_qualifier@ identifier s; @@ static struct hw s = {...};

@ref@ position p; identifier match.s; @@ s@p

@good1@ position ref.p; identifier match.s,f,c; expression e; @@ ( e = s@p | e = s@p.f | c(...,s@p.f,...) | c(...,s@p,...) )

@bad depends on !good1@ position ref.p; identifier match.s; @@ s@p

@depends on forall !bad disable optional_qualifier@ identifier match.s; @@ static + const struct hw s;
