Subject: [PATCHv5 01/16] arm: arch_timer: balance device_node refcounting
Date: Thu, 31 Jan 2013 12:15:24 +0000 [thread overview]
Message-ID: <1359634539-9580-2-git-send-email-mark.rutland@arm.com> (raw)
In-Reply-To: <1359634539-9580-1-git-send-email-mark.rutland@arm.com>
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.
