If anyone has any objections, please let me know. ------------------ From: Aurabindo Pillai commit ba93dddfc92084a1e28ea447ec4f8315f3d8d3fd upstream. With HostVM enabled, DCN31 fails to pass validation for 3x4k60. Some Linux userspace does not downgrade one of the monitors to 4k30, and the result is that the monitor does not light up. Disable it until the bandwidth calculation failure is resolved.
