[Qemu-devel] Re: [PATCH V10 01/27] acpi: split out pc smbus routines from acpi.c into pc_smbus.c

[Gerd Hoffmann]

+void pc_smbus_init(PCSMBus *smb)
+{
+    smb->smbus = i2c_init_bus(NULL, "i2c");
+}

This function should take a additional "DeviceState *parent" argument 
and pass it down to i2c_init_bus() instead of NULL.  Patch #21 
(acpi_piix4: qdevfy) should pass the piix4-pm DeviceState to 
pc_smbus_init().  Then the smbus and all connected devices should be 
correctly hooked up in the device tree and visible in 'info qtree'.

cheers,
  Gerd
