| |
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> --- There is also an extra of_node_put() before a continue in the same loop on line 1001 of this file which should be deleted. Julia Lawall has already sent a patch to delete this but if preferred I can send one patch to do both the changes.
