From deb387d4af5a4be3b656b5d69ae4d87ccee325b8 Mon Sep 17 00:00:00 2001 From: Maxime Ripard Date: Fri, 15 Mar 2019 10:22:47 +0100 Subject: [PATCH] of: property: Document that of_graph_get_endpoint_by_regs needs of_node_put The node returned by of_graph_get_endpoint_by_regs has a reference taken, and we need to put that reference back when done with the node. However, the documentation for that node doesn't mention it, so let's make sure it does.
