From 2b55d10c46815d9660c0f1bc6044f7019ff384aa Mon Sep 17 00:00:00 2001 From: Mark Rutland Date: Wed, 19 Dec 2012 11:37:49 +0000 Subject: [PATCH] arm: arch_timer: balance device_node refcounting When we get the device_node for the arch timer, it's refcount is automatically incremented in of_find_matching_node, but it is never decremented. This patch decrements the refcount on the node after we're finished using it.
