From d36f165d9523a5d151f11888938fcc66a6dd10df Mon Sep 17 00:00:00 2001 From: Paolo Bonzini Date: Fri, 18 Oct 2024 11:18:25 +0200 Subject: qdev: make properties array "const" Constify all accesses to qdev properties, except for the ObjectPropertyAccessor itself. This makes it possible to place them in read-only memory, and also lets Rust bindings switch from "static mut" arrays to "static"; which is advantageous, because mutable statics are highly discouraged.
