of: platform: fix OF node refcount leak
We need to call of_node_put() for device nodes obtained with of_find_node_by_path(). Fixes: 3aa0582fdb82 ("of: platform: populate /firmware/ node from of_platform_default_populate_init()") Reported-by: Loys Ollivier <lollivier@baylibre.com> Cc: Frank Rowand <frowand.list@gmail.com> Signed-off-by: Sudeep Holla <sudeep.holla@arm.com> Acked-by: Rob Herring <robh@kernel.org> Signed-off-by: Andy Gross <andy.gross@linaro.org> Signed-off-by: Arnd Bergmann <arnd@arndb.de>
