memory: tegra: mc: Add missing of_node_put()
for_each_child_of_node() performs an of_node_get() on each iteration, so to break out of the loop an of_node_put() is required. Found using Coccinelle. The semantic patch used for this is as follows: // <smpl> @@ expression e; local idexpression n; @@ for_each_child_of_node(..., n) { ... when != of_node_put(n) when != e = n ( return n; | + of_node_put(n); ? return ...; ) ... } // </smpl> Signed-off-by: Amitoj Kaur Chawla <amitoj1606@gmail.com> Signed-off-by: Thierry Reding <treding@nvidia.com>
