From f4bbaaf584ed8d0a430b467bace15f338cba4c57 Mon Sep 17 00:00:00 2001 From: Markus Armbruster Date: Tue, 17 Feb 2015 14:28:02 +0100 Subject: [PATCH] usb: Propagate errors through usb_register_companion() This loses the messages explaining the error printed with error_printf_unless_qmp(). The next commit will make up for the loss.
