From 38255efffe393ce6242b21965b92ac06a0aae6c8 Mon Sep 17 00:00:00 2001 From: Eduardo Habkost Date: Fri, 11 Dec 2020 17:05:11 -0500 Subject: qdev: Move UUID property to qdev-properties-system.c Only softmmu code uses DEFINE_PROP_UUID, and it currently depends on error_set_from_qdev_prop_error(). Move it to qdev-properties-system.c to get out of our way when refactoring the qdev property system. We can eventually move it back to the core property system later, after removing usage of error_set_from_qdev_prop_error().
