PCI: tegra: Fix OF node reference leak [ Upstream commit 9e38e690ace3e7a22a81fc02652fc101efb340cf ] Each iteration of for_each_child_of_node() executes of_node_put() on the previous node, but in some return paths in the middle of the loop of_node_put() is missing thus causing a reference leak. Hence stash these mid-loop return values in a variable 'err' and add a new label err_node_put which executes of_node_put() on the previous node and returns 'err' on failure. Change mid-loop return statements to point to jump to this label to fix the reference leak. Issue found with Coccinelle.
