Changes in this version: Used connector->atomic_check() to release vcpi slots instead of the atomic_release() callback.
This series introduces void * type driver-private objects in core and adds helper functions that operate on these private objects. Drivers need to implement object-specific functions to swap and clear object states. The advantage of having void * for these objects in the core is objects of different types can be managed in the same atomic state array. The series implements DP-MST link bw tracking using the driver-private object infrastructure.
