From 034bf091b7a5f02e63409b0b5b6dad1101d70144 Mon Sep 17 00:00:00 2001 From: Pantelis Antoniou Date: Tue, 8 Jan 2013 15:31:42 +0200 Subject: [PATCH] ARM: OMAP2+: DT node Timer iteration fix The iterator correctly handles of_node_put() calls. Remove it before continue'ing the loop. Without this patch you get the following with CONFIG_OF_DYNAMIC set: ERROR: Bad of_node_put() on /ocp/timer@44e31000!
