Dear Dmitry,

For context, I have a Lenovo Yoga Slim 7x laptop, and was having issues with the display staying black after sleep. As a workaround, I could switch to a different VT and back.

[ 1185.831970] [dpu error]connector not connected 3

I can confirm that I was seeing this exact error message as well.

  	if (!conn_state || !conn_state->connector) {
  		DPU_ERROR("invalid connector state\n");
  		return -EINVAL;
-	} else if (conn_state->connector->status != connector_status_connected) {
-		DPU_ERROR("connector not connected %d\n", conn_state->connector->status);
-		return -EINVAL;
  	}
crtc = conn_state->crtc;

After applying this patch, the screen now resumes successfully, and the errors are gone.

(For future reference, I am using this kernel: https://github.com/jhovold/linux/commits/wip/x1e80100-6.11-rc5/, commit cc2cb95cc77fec43edd407c993122085fa8c2dd7.)
