The 'altmodes_node' fwnode_handle is never released after it is no longer required, which leaks the resource.
Add the required call to fwnode_handle_put() when 'altmodes_node' is no longer required.

Sorry to go back to this, but I guess we should actually use those scope based helpers with fwnodes in this case. So instead of a dedicated fwnode_handle_put() call like that, just introduce altmodes_node like this:
... struct fwnode_handle *altmodes_node __free(fwnode_handle) = device_get_named_child_node(&port->dev, "altmodes"); if (IS_ERR(altmodes_node)) return; fwnode_for_each_child_node(altmodes_node, child) { ...thanks,
That would have to be a second patch, because it does not apply to all affected stable kernels. I can send it separately, though.
Great, thanks!
