From 67980031d234aa90524b83bb80bb5d1601d29076 Mon Sep 17 00:00:00 2001 From: "Dr. David Alan Gilbert" Date: Thu, 2 Feb 2017 12:59:56 +0000 Subject: [PATCH] vmstate registration: check return values Check qdev's call to vmstate_register_with_alias_id; that gets most of the common uses; there's hundreds of calls via vmstate_register which could get fixed over time.
