From: Colin Ian King <colin.king@xxxxxxxxxxxxx>
Currently when there are other connectors on the port using HDCP the
function _intel_hdcp_disable returns a garbage uninitialized value in
variable ret. I believe the intention is to return 0, so return this
literal value instead of the value in ret.
Addresses-Coverity: ("Uninitialized scalar return")
Fixes: 899c8762f981 ("drm/i915/hdcp: Configure HDCP2.2 MST steram encryption status")
