I posted this series as RFC back in October, but it depended on
patches then still under review, so I put it aside, and promptly
forgot. Fortunately, rebasing and updating it wasn't much trouble.
While discussing Gonglei's "[PATCH v2 00/19] usb: convert device init
to realize", Paolo called the PCI conversion job "Gargantuan". This
series attempts to crack it into manageable jobs.
The basic idea comes from qdev core: have the core deal with just
realize, but default the device models' realize() method to one that
calls the old init() method. Unconverted device models don't set
their realize(), thus get one that calls their init(). We can then
convert device by device instead of having to convert of all of PCI in
one Gargantuan go.
Since PCI's exit() cannot fail, I chose not to add an unrealize().
Precedence: USBDeviceClass method handle_destroy(), called on USB
unrealize.
Aside: USBDeviceClass also has an unrealize() method, but it's never
set and never called.
PATCH 01 converts the interface between PCI core and qdev to realize.
PATCH 02 adds realize to the interface between PCI core and PCI device
models. Once all device models are converted to realize, the old init
interface can be dropped, completing the Gargantuan job.
PATCH 03-04 convert device models that cannot fail initialization.
PATCH 05-10 convert a few that can fail, but are really easy to
convert.
