media_entity_graph_walk_start — Start walking the media graph at a given entity
void media_entity_graph_walk_start ( | struct media_entity_graph * graph, |
struct media_entity * entity); |
Before using this function, media_entity_graph_walk_init must be
used to allocate resources used for walking the graph. This
function initializes the graph traversal structure to walk the
entities graph starting at the given entity. The traversal
structure must not be modified by the caller during graph
traversal. After the graph walk, the resources must be released
using media_entity_graph_walk_cleanup.
