I mean it is the registration function provided by the subsystem that
owns the class, for instance tpm_chip_register(),
ib_register_device(), register_netdev(), rtc_register_dev...

[PATCH V2 3/5] vDPA: introduce vDPA bus
...s the subsystem core is
badly done wrong.
The 'class' is supposed to provide all the library functions to remove
this duplication. Instead of plugging the HW driver in via some bus
scheme every subsystem has its own 'ops' that the HW driver provides
to the subsystem's class via subsystem_register()
This is the *standard* pattern to use the driver core.
This is almost there, it just has this extra bus part to convey the HW
ops instead of directly.

Sure, but plugging in via ops/etc not via a bus and...

Hmm I'm not familiar with subsystem_register. A grep didn't find it
in the kernel either ...
