struct_size() macro first argument is structure pointer, so above will 
not work as it is.

I agree that we could use struct_size() in some cases, but in this 
particular case we will endup with more local pointer variables that are 
just declared to keep struct_size() macro happy.

IMO, Which will not make code any better than what it is now.

I will revist these and see if it makes sense to use it in other places.

I agree, will try find such instances and fix them before I send out 
next version.

These are mostly u32 it did work without packed, but I agree with you on 
missing __packed. Will fix such instances.
