From 3713e1485e6eace7d48b9c790602cfd92c616e5f Mon Sep 17 00:00:00 2001 From: Hans de Goede Date: Fri, 15 Mar 2013 11:52:37 +0100 Subject: usb-redir: Fix crash on migration with no client connected If no client is connected on the src side, then we won't receive a parser during migrate, in this case usbredir_post_load() should be a nop, rather then to try to derefefence the NULL dev->parser pointer.
