I get the following build error on my system with this applied:

  CC [M]  drivers/usb/typec/mux/nb7vpq904m.o
drivers/usb/typec/mux/nb7vpq904m.c: In function ‘nb7vpq904m_register_bridge’:
drivers/usb/typec/mux/nb7vpq904m.c:327:20: error: ‘struct drm_bridge’ has no member named ‘of_node’
  327 |         nb7->bridge.of_node = nb7->client->dev.of_node;
      |                    ^


What went wrong?

thanks,
