From acd418bfcfc415cf5e6414b6d1c6acfec850f290 Mon Sep 17 00:00:00 2001 From: Daniel Scally Date: Thu, 7 Jan 2021 14:28:27 +0100 Subject: [PATCH] media: device property: Call fwnode_graph_get_endpoint_by_id() for fwnode->secondary This function is used to find fwnode endpoints against a device. In some instances those endpoints are software nodes which are children of fwnode->secondary. Add support to fwnode_graph_get_endpoint_by_id() to find those endpoints by recursively calling itself passing the ptr to fwnode->secondary in the event no endpoint is found for the primary.
