drivers/gpu/drm/i915/display/intel_hdcp.c:886 _intel_hdcp_disable() error: uninitialized symbol 'ret'.
drivers/gpu/drm/i915/display/intel_hdcp.c:1951 _intel_hdcp2_disable() error: uninitialized symbol 'ret'.
Given the comment that this error reflects the status of all connectors
within this MST topology, I opted to use -EBUSY to indicate not all were
ready.
Fixes: 2a743b7b8a8b ("drm/i915/hdcp: Configure HDCP1.4 MST steram encryption status")
Fixes: 899c8762f981 ("drm/i915/hdcp: Configure HDCP2.2 MST steram encryption status")
