From 64a7b8de42aff54dce4d82585f25060a741531d1 Mon Sep 17 00:00:00 2001 From: Felipe Franciosi Date: Tue, 4 Feb 2020 13:16:01 +0000 Subject: qom/object: Use common get/set uint helpers MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Several objects implemented their own uint property getters and setters, despite them being straightforward (without any checks/validations on the values themselves) and identical across objects. This makes use of an enhanced API for object_property_add_uintXX_ptr() which offers default setters. Some of these setters used to update the value even if the type visit failed (eg. because the value being set overflowed over the given type). The new setter introduces a check for these errors, not updating the value if an error occurred. The error is propagated.
