ARM9 = video core here? May be commit text needs little bit more detail.

No need of casting.

+ if (of_device_is_compatible(dev->of_node, "qcom,venus-pil-no-tz"))
+ core->fw.dev = dev;
+
+ return 0;
+}

- ret = venus_boot(dev, core->res->fwname);
+ ret = of_platform_populate(dev->of_node, NULL, NULL, dev);
+ if (ret)
+ goto err_runtime_disable;
+
+ /* Attempt to register child devices */
+ ret = device_for_each_child(dev, core, store_firmware_dev);
+

and not ret check needed?

+ ret = venus_boot(core);
if (ret)
goto err_runtime_disable;
