Subject: [PATCH 02/12] macfb: fix invalid object reference in macfb_common_realize()
Date: Sat,  2 Oct 2021 11:59:57 +0100	[thread overview]
Message-ID: <20211002110007.30825-3-mark.cave-ayland@ilande.co.uk> (raw)
In-Reply-To: <20211002110007.30825-1-mark.cave-ayland@ilande.co.uk>

During realize memory_region_init_ram_nomigrate() is used to initialise the RAM
memory region used for the framebuffer but the owner object reference is
incorrect since MacFbState is a typedef and not a QOM type.

Change the memory region owner to be the corresponding DeviceState to fix the
issue and prevent random crashes during macfb_common_realize().
