[Qemu-devel] [PATCH 043/156] Fix vmstate_info_int32_le comparison/assign |

From: "Dr. David Alan Gilbert" <address@hidden>
Fix comparison of vmstate_info_int32_le so that it succeeds if loaded
value is (l)ess than or (e)qual
When the comparison succeeds, assign the value loaded
This is a change in behaviour but I think the original intent, since
the idea is to check if the version/size of the thing you're loading is
less than some limit, but you might well want to do something based on
the actual version/size in the file
Fix up comment and name text
