This v9 version has fixed crome-os NULL pointer dereference
by just reordering connector status condition.
It has been tested manually with below IGT series on TGL and ICL.

[PATCH v9 12/19] misc/mei/hdcp: Fix AUTH_STREAM_REQ cmd buffer len
has an Ack from Tomas to merge it via drm-intel.

[PATCH v9 13/19] drm/hdcp: Max MST content streams
has an Ack from drm-misc maintainer to merge it via drm-intel.

Test-with: 20201126050320.2434-2-karthik.b.s at intel.com
