Subject: soc/tegra: fuse: Add missing of_node_put()
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=0a3c2dbec425b82d9af7aeb5dc9b18da398992a7;p=linux.git

soc/tegra: fuse: Add missing of_node_put()

In tegra_init_apbmisc(), of_find_matching_node() will return a node
pointer with refcount incremented. We should use of_node_put() in each
failure path or when it is not used anymore.
