Subject: clk: nomadik: Add missing of_node_put()
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=28a0b0984e76df8fd64b6850fa56cf5201e6e638;p=linux.git

clk: nomadik: Add missing of_node_put()

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