From 91b577aa8752e5dbeaf306a798121fa5ee60714d Mon Sep 17 00:00:00 2001 From: Amit Shah Date: Wed, 7 Oct 2009 18:31:17 +0530 Subject: [PATCH] char: emit the OPENED event only when a new char connection is opened The OPENED event gets sent also when qemu resets its state initially. The consumers of the event aren't interested in receiving this event on reset.
