From bf416bd457389bfe7371ba9074bcbd032d7a04cc Mon Sep 17 00:00:00 2001 From: Krzysztof Kozlowski Date: Wed, 21 May 2014 13:22:59 +0200 Subject: [PATCH] clk: s2mps11: Add missing of_node_put and of_clk_del_provider Add of_clk_del_provider to remove previously registered clock provider. Add of_node_put to decrement the ref count of clock nodes.
