Maxime Ripard 44fe9f90eb drm/vc4: hdmi: Only call into DRM framework if registered ... Our hotplug handler will currently call the drm_kms_helper_hotplug_event every time a hotplug interrupt is called. However, since the device is registered after all the drivers have finished their bind callback, we have a window between when we install our interrupt handler and when drm_dev_register() is eventually called where our handler can run and call drm_kms_helper_hotplug_event but the device hasn't been registered yet, causing a null pointer dereference. Fix this by making sure we only call drm_kms_helper_hotplug_event if our device has been properly registered.
