Re: [PATCH] usb: core: add missing of_node_put() in usb_of_has_devices_or_graph

Quoting Javier Carrasco (2024-06-24 14:10:06)

The for_each_child_of_node() macro requires an explicit call to of_node_put() on early exits to decrement the child refcount and avoid a memory leak. The child node is not required outsie the loop, and the resource must be released before the function returns.

Add the missing of_node_put().
