powerpc/cell: add missing of_node_put
for_each_node_by_name performs an of_node_get on each iteration, so a break out of the loop requires an of_node_put. A simplified version of the semantic patch that fixes this problem is as follows (http://coccinelle.lip6.fr): // <smpl> @@ expression e,e1; local idexpression n; @@ for_each_node_by_name(n, e1) { ... when != of_node_put(n) when != e = n ( return n; | + of_node_put(n); ? return ...; ) ... } // </smpl> Signed-off-by: Julia Lawall <Julia.Lawall@lip6.fr> Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> Link: https://lore.kernel.org/r/1448051604-25256-7-git-send-email-Julia.Lawall@lip6.fr
