Atomic changes broke check_digital_port_conflicts(). It needs to look at the global situation instead of just trying to find a conflict within the current atomic state. This bug made my HSW explode spectacularly after I had split the DDI encoders into separate DP and HDMI encoders. With the fix, things seem much more solid. I hope holding the connection_mutex is enough protection that we can actually walk the connectors even if they're not part of the current atomic state... v2: Regenerate the patch so that it actually applies (Jani) Cc: stable@vger.kernel.org Cc: Ander Conselvan de Oliveira <ander.conselvan.de.oliveira@intel.com> Fixes: 5448a00d ("drm/i915: Don't use staged config in check_digital_port_conflicts()") Signed-off-by:
