Hi everyone,
This series allow to configure one or more VKMS instances without having
to reload the driver using configfs.
The series is structured in 3 blocks:

available options as minimal as possible.

When a connector is created, add a `status` file to allow to update the
connector status to:
- 1 connector_status_connected
- 2 connector_status_disconnected
- 3 connector_status_unknown
If the device is enabled, updating the status hot-plug or unplugs the
connector.

In cdv_intel_dp_get_modes(), the return value of drm_mode_duplicate()
is assigned to mode, which will lead to a NULL pointer dereference on
failure of drm_mode_duplicate(). Add a check to avoid npd.
This is similar to the fix commit cb520c3f366c
("drm/gma500: fix null pointer dereference in cdv_in
This is the new API for allocating DRM bridges.
