From 4e4f485c89c95c317fadf9faf76d703f0cc7a34d Mon Sep 17 00:00:00 2001 From: Julia Lawall Date: Fri, 9 Oct 2015 19:47:41 +0200 Subject: [PATCH] clk: tegra: delete unneeded of_node_put for_each_child_of_node performs an of_node_put on each iteration, so putting an of_node_put before a continue results in a double put.
