[PATCH 0/3] ppc: Fixes for class and instance size problems

[David Gibson]

As requested, some fixes for the ppc things found by Eduardo's
scripts.

Cédric Le Goater (1):
  ppc/pnv: Fix TypeInfo of PnvLpcController abstract class

David Gibson (2):
  adb: Correct class size on TYPE_ADB_DEVICE
  spapr: Correct type for SPAPR_DRC_PCI

[PATCH 1/3] adb: Correct class size on TYPE_ADB_DEVICE

[David Gibson]

The TypeInfo incorrectly just lets the class size be inherited.  It won't
actually break things, since the class is abstract, but we should get it
right.

[PATCH 2/3] ppc/pnv: Fix TypeInfo of PnvLpcController abstract class

[David Gibson]

From: Cédric Le Goater <clg@kaod.org>

It was missing the instance_size field.

[PATCH 3/3] spapr: Correct type for SPAPR_DRC_PCI

[David Gibson]

TYPE_SPAPR_DRC_PCI inherits from TYPE_SPAPR_DRC_PHYSICAL, so its checker
macro should use the corresponding instance type.  We got away with it
because we never actually used that checker macro.

I'm not sure this is really what we want to do.  This is what
triggered the warning in my script, but it doesn't mean we want
to use SpaprDrcPhysical here.

Code that needs a SpaprDrc* can use SPAPR_DR_CONNECTOR();
code that needs a SpaprDrcPhysical* can use SPAPR_DRC_PHYSICAL().
All the other OBJECT_CHECK(SpaprDrc, ...) and
OBJECT_CHECK(SpaprDrcPhysical, ...) macros seem unnecessary.

Good point.  I've rewritten and am resending.
