tee: optee: add missing of_node_put after of_device_is_available
Add an of_node_put when a tested device node is not available.
The semantic patch that fixes this problem is as follows
(http://coccinelle.lip6.fr):
// <smpl>
@@
identifier f;
local idexpression e;
expression x;
@@
e = f(...);
... when != of_node_put(e)
when != x = e
when != e = x
when any
if (<+...of_device_is_available(e)...+>) {
... when != of_node_put(e)
(
return e;
|
+ of_node_put(e);
return ...;
)
}
// </smpl>
Fixes: db878f76b9ff ("tee: optee: take DT status property into account")
