[PATCH 0/3] driver core: class: remove class_compat code

[Heiner Kallweit <hkallweit1@gmail.com>]

vfio/mdev is the last user of class_compat, and it doesn't use it for
the intended purpose. See kdoc of class_compat_register():
Compatibility class are meant as a temporary user-space compatibility
workaround when converting a family of class devices to a bus devices.

In addition it uses only a part of the class_compat functionality.
So inline the needed functionality, and afterwards all class_compat
code can be removed.

Heiner Kallweit (3):
  driver core: class: add class_pseudo_register
  vfio/mdev: inline needed class_compat functionality
  driver core: class: remove class_compat code
