[ Upstream commit 47918bc68b7427e961035949cc1501a864578a69 ]
In update_lmb_associativity_index() we lookup dr_node using of_find_node_by_path() which takes a reference for us. In the non-error case we forget to drop the reference. Note that find_aa_index() does modify properties of the node, but doesn't need an extra reference held once it's returned.
