From f11552d030e8e5a0a945b1920e31eaf48fe3fad4 Mon Sep 17 00:00:00 2001 From: Nicholas Mc Guire Date: Tue, 12 Jun 2018 13:23:16 -0400 Subject: [PATCH] media: stm32-dcmi: simplify of_node_put usage This does not fix any bug - this is just a code simplification. As np is not used after passing it to v4l2_fwnode_endpoint_parse() its refcount can be decremented immediately and at one location.
