pinctrl_register returns an ERR_PTR on error.
The Coccinelle semantic patch used to make this change is as follows:
@@
expression e,e1,e2;
@@
e = pinctrl_register(...)
... when != e = e1
if (
- e == NULL
+ IS_ERR(e)
) {
...
return
- e2
+ PTR_ERR(e)
;
}

I already have a patch like this in my tree it seems.
But very nice that cocinelle is now finding this!
