[Qemu-devel] [PATCH v2 0/4] Convert to realize()

[Cao jin]

v2 changelog:
1. separate every supporting function into a single patch
2. Change supporting function type to void, for consistency
3. other fixes as per Stefano`s review

@Stefano: the last patch build failure you feedback:

qemu/hw/xen/xen_pt_config_init.c: In function ‘xen_pt_config_init’:
qemu/hw/xen/xen_pt_config_init.c:2061:42: error: ‘rc’ may be used uninitialized 
in this func

I admit it is careless misktake(fixed), but weird thing is, I confirmed
again, it indeed can compile in my environment, the evidence is:
1. every time I make after touching xen_pt_config_init.c, I can see the log:
    CC    x86_64-softmmu/hw/xen/xen_pt_config_init.o
    LINK  x86_64-softmmu/qemu-system-x86_64
2. $ readelf -s qemu-system-x86_64 | grep xen_pt_config_init , can got the
   symbol

Will the different compiler make the difference?(I am using
gcc (GCC) 4.9.2 20150212 (Red Hat 4.9.2-6))

Cao jin (4):
  Add Error **errp for xen_host_pci_device_get()
  Add Error **errp for xen_pt_setup_vga()
  Add Error **errp for xen_pt_config_init()
  Xen PCI passthru: convert to realize()
