This one here is good imo, and has my Reviewed-by: Daniel Vetter <daniel.vetter@xxxxxxxx>

+ DRM_HDCP_TOPOLOGY_CHANGE,
+ DRM_HDCP_LINK_INTEGRITY_FAILURE,
+ DRM_HDCP_REAUTH_REQUEST
+};
But this one here is just a part of the intel_hdcp_shim interface. I think
we should put into the intel_drv.h header, and change the return value of
the check_2_2_link hook to this enum. I think that would clarify the code
a lot. Plus then ofc merge this part into the first patch that uses it.
daniel,
this is generic link check results as per the HDCP spec. This could be used
by any other driver in DRM. Still should i move as local to intel?
Yeah I think makes more sense. intel_hdcp_shim could also be used as
fairly generic hdcp implementation, but right now it isn't. Better to keep
things together that are used together.
thanks. With this i will use your R-b ?

With that remaining patches have my ack, too.
