I doubt that moving the struct members around is safe.  This looks like
it's in a very specific order.  So I don't think this patch is correct.

The reason for this false positive this code uses a #pragma to pack the
struct.

#pragma pack(push, 1) // PF2VF / VF2PF data areas are byte packed

Sparse does not support this and Smatch uses Sparse as a parser.  The
main reason why Sparse doesn't support this pragma is because Linus
thinks it's gross.  You probably didn't even see the #pragma did you?
And anything you can't see is unreadable by definition.

"Mark the associated types properly packed individually, rather than
use the disgusting "pragma pack()" that should never be used."

Marking the structs packed could be very simple.

Oh, Sorry, I didn't see this code.

This patch is error, and sorry for the noise.
