From: Bernhard Beschow Date: Mon, 13 Feb 2023 16:19:56 +0000 (+0100) Subject: hw/pci-host/i440fx: Inline sysbus_add_io() X-Git-Tag: v8.1.0-rc0~110^2~12 X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=273d65020b04f8a01e4b5cd543aeef1624b17001;p=thirdparty%2Fqemu.git hw/pci-host/i440fx: Inline sysbus_add_io() sysbus_add_io() just wraps memory_region_add_subregion() while also obscuring where the memory is attached. So use memory_region_add_subregion() directly and attach it to the existing memory region s->bus->address_space_io which is set as an alias to get_system_io() by the pc machine.
