Current behavior?

Possible null pointer dereference may occur because of missing return in error check:

tensorflow/tensorflow/compiler/mlir/tensorflow/transforms/extract_tpu_copy_with_dynamic_shape_op.cc

Lines 61 to 65 in 63bb733

	auto launch_op = llvm::dyn_cast<tf_device::LaunchOp>(op->getParentOp());
	if (!launch_op) {
	op->emitError() << "TPUCopyWithDynamicShapeOp is not in a launch";
	}
	std::string device_str = launch_op.getDeviceAttr().getValue().str();
