I've applied both patches, and am testing on a machine with DVI-I and
DisplayPort.

Test sequence:

1) Boot system with no outputs connected.
2) Attach a DVI-D monitor, then remove it.
3) Attach a DVI-A to VGA adapter that has no load, then remove it.
4) Attach a DVI-A to VGA adapter that has load but no DDC, then remove it.
5) Attach a DVI-A to VGA adapter that has load and DDC, then remove it.
6) Repeat steps 2 to 5, watching for uevents.

Note that the DVI-A to VGA adapter asserts HPD when connected.

Results:

DVI-D hotplug works fine. There is a delay on the first DVI-D hotplug after the
connector has been used for VGA, but I get an event within 10 seconds.

No events when I plug in the adapter with no load and wait 20 seconds.

No events when I plug in the adapter with load but not DDC and wait 20 seconds.

Events on connect only when I plug in the adapter with DDC.
