[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] [PATCH 14/36] qdev: Move dev->realized check to qdev_property_set()
Every single qdev property setter function manually checks
dev->realized. We can just check dev->realized inside
qdev_property_set() instead.
The check is being added as a separate function
(qdev_prop_allow_set()) because it will become a callback later.
