of_get_next_parent — iterate to a node's parent
struct device_node * of_get_next_parent ( | struct device_node * node) ; |
Find the parent node of node.
This is like of_get_parent
except that it drops the
refcount on the passed node, making it suitable for iterating
up the tree.
Pointer to next parent node pointer if found, with refcount
incremented, use of_node_put
on it when done. NULL if node
is not found.
