Imre Deak deae1e6365 drm/dp_mst: Don't report ports connected if nothing is attached to them ... commit 873e5bb9fb upstream. Reporting a port as connected if nothing is attached to them leads to any i2c transactions on this port trying to use an uninitialized i2c adapter, fix this. Let's account for this case even if branch devices have no good reason to report a port as plugged with their peer device type set to 'none'.
