The current output code only supports connection to drm panels. Add code to support drm bridge, to support connections to external connectors.

Since you need np here again, you need to move the of_node_put above back into the if statement...
- of_node_put(np);
- if (!bridge)
return -ENODEV;- fsl_dev->encoder.bridge = bridge;
- bridge->encoder = &fsl_dev->encoder;
- ret = drm_bridge_attach(fsl_dev->drm, bridge);
- return ret;
Also simplify this return statement.
