Subject: [PATCH 02/12] hw/arm/raspi: Avoid using TypeInfo::class_data pointer
Date: Sat, 15 Feb 2020 20:15:33 +0100	[thread overview]
Message-ID: <20200215191543.3235-3-f4bug@amsat.org> (raw)
In-Reply-To: <20200215191543.3235-1-f4bug@amsat.org>

Using class_data pointer to create a MachineClass is not
the recommended way anymore. The correct way is to open-code
the MachineClass::fields in the class_init() method.

This partly reverts commit a03bde3674e.

Suggested-by: Igor Mammedov <imammedo@redhat.com>
