[Qemu-devel] [PATCH 1/1] vmstate-static-checker: fix size mismatch detection in unused fields

[Amit Shah <amit.shah@redhat.com>]

If a field changed from something to unused, the checker wasn't flagging
if the field size mismatched.  This was noticed in:

http://thread.gmane.org/gmane.comp.emulators.qemu/419802

where the 4->1 size change along with field name change to 'unused'
wasn't being flagged.  Fix this.
