Just a doubt on my side.
We don't need an error path to free ctrl_hdlr?
Or I'm missing something?
Something similar:
ret = v4l2_fwnode_device_parse(imx335->dev, &props);
if (ret)
goto free_ctrls;
ret = v4l2_ctrl_new_fwnode_properties(ctrl_hdlr, &imx335_ctrl_ops,
&props);
if (ret)
return ret;
free_ctrls:
v4l2_ctrl_handler_free(hdl);
return ret;
Thanks & Regards,
Tommaso
