From df4fe0b291b2baf1694517a4a67be7525102656b Mon Sep 17 00:00:00 2001 From: Markus Armbruster Date: Tue, 5 May 2020 17:29:26 +0200 Subject: [PATCH] qom: Drop @errp parameter of object_property_del() MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Same story as for object_property_add(): the only way object_property_del() can fail is when the property with this name does not exist. Since our property names are all hardcoded, failure is a programming error, and the appropriate way to handle it is passing &error_abort. Most callers do that, the commit before previous fixed one that didn't (and got the error handling wrong), and the two remaining exceptions ignore errors. Drop the @errp parameter.
