CVE-2022-49644

Summary

In the Linux kernel, the following vulnerability has been resolved:

drm/i915: fix a possible refcount leak in intel_dp_add_mst_connector()

If drm_connector_init fails, intel_connector_free will be called to take care of proper free. So it is necessary to drop the refcount of port before intel_connector_free.

(cherry picked from commit cea9ed611e85d36a05db52b6457bf584b7d969e2)
