Subject: [PATCH 1/2] qom: Declare class_base_init() before class_init()
Date: Sat, 25 Jan 2025 17:58:54 +0100	[thread overview]
Message-ID: <20250125165855.32168-2-philmd@linaro.org> (raw)
In-Reply-To: <20250125165855.32168-1-philmd@linaro.org>

Since class_base_init() is called *before* class_init(),
move its declaration in TypeInfo before class_init() to
help a bit. No logical change.
