[PATCH 03/11] qemu: Move qemuDomainUpdateDeviceLive() into qemu_hotplug.c

[PATCH 03/11] qemu: Move qemuDomainUpdateDeviceLive() into qemu_hotplug.c
Posted by Michal Privoznik 1 year, 7 months ago
There is no good reason for qemuDomainUpdateDeviceLive() to live
in (ever growing) qemu_driver.c while we have qemu_hotplug.c
which already contains the rest of hotplug code. Move the
function to its new home.
