From 99ba777e53ebf31bf24e7a52a21fccdd25f95537 Mon Sep 17 00:00:00 2001 From: Markus Armbruster Date: Wed, 10 Jun 2020 07:32:00 +0200 Subject: qdev: Convert uses of qdev_set_parent_bus() with Coccinelle MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit In addition to the qdev_create() patterns converted so far, we have a qdev_set_parent_bus() pattern. Mostly when we embed a device in a parent device rather than allocating it on the heap. This pattern also puts devices in the dangerous "no QOM parent, but plugged into bus" state I explained in recent commit "qdev: New qdev_new(), qdev_realize(), etc." Apply same solution: convert to qdev_realize(). Coccinelle script: @@ expression dev, bus, errp; symbol true; @@ - qdev_set_parent_bus(DEVICE(dev), bus); ... - object_property_set_bool(OBJECT(dev), true, "realized", errp); + qdev_realize(DEVICE(dev), bus, errp); @ depends on !(file in "qdev-monitor.c") && !(file in "hw/core/qdev.c")@ expression dev, bus, errp; symbol true; @@ - qdev_set_parent_bus(dev, bus); ... - object_property_set_bool(OBJECT(dev), true, "realized", errp); + qdev_realize(dev, bus, errp); @@ expression dev, bus; symbol true; @@ - qdev_set_parent_bus(DEVICE(dev), bus); ... - qdev_init_nofail(DEVICE(dev)); + qdev_realize(DEVICE(dev), bus, &error_fatal); Unconverted uses of qdev_set_parent_bus() remain. They'll be converted later in this series.
