| |
In spear_setup_of_timer(), of_find_matching_node() will return a node pointer with refcount incrementd. We should use of_node_put() in each fail path or when it is not used anymore.
Signed-off-by: Liang He <windhl@126.com> --- changelog: v2: use goto-label patch style suggested by Viresh. v1: use plain of_node_put in each fail path.
