------------------

From: Mitul Golani <mitulkumar.ajitkumar.golani@intel.com>

commit eb53e5b933b9ff315087305b3dc931af3067d19c upstream.

AS SDP should be computed when VRR timing generator is also enabled.
Correct the compute condition to compute params of Adaptive sync SDP
when VRR timing genrator is enabled along with sink support indication.

--v2:
Modify if condition (Jani).
