From d3c4931647c16c2ffc09a2c7c80d71c73cd026c6 Mon Sep 17 00:00:00 2001 From: Peter Crosthwaite Date: Thu, 25 Sep 2014 22:19:19 -0700 Subject: [PATCH] qom: Allow clearing of a Link property By passing in "" to object_property_set_link. The lead user of this is the QDEV GPIO framework which will implement GPIO disconnects via an "unlink". GPIO disconnection is used by qtest's irq_intercept_out command.
