From 7781b88ee458ff933459503ade0b0a6ddaad08de Mon Sep 17 00:00:00 2001 From: Marc-André Lureau Date: Mon, 21 Oct 2019 23:32:12 +0200 Subject: serial: initial qom-ification Make SerialState a device (the following patches will introduce IO/MM sysbus serial devices) None of the serial_{,mm}_init() callers actually free the returned value (even if they did, it would be quite harmless), so we can change the object allocation at will. However, the devices that embed SerialState must now have their field QOM-initialized manually (isa, pci, pci-multi).
