[ros-diffs] [cfinck] 33357: Filip Navara: - Only increment VideoPortDeviceNumber, when IntVideoPortCreateAdapterDeviceObject and IntVideoPortFindAdapter succeeded. This fixes loading the CL54xx miniport driver. But it still isn't usable, because win32k cannot find the DDI driver for it.

Filip Navara:
- Only increment VideoPortDeviceNumber, when IntVideoPortCreateAdapterDeviceObject and
IntVideoPortFindAdapter succeeded.
  This fixes loading the CL54xx miniport driver. But it still isn't usable, because
win32k cannot find the DDI driver for it.
