devm_pinctrl_register returns an ERR_PTR in case of error and should
have an IS_ERR check instead of a null check.
The Coccinelle semantic patch used to make this change is as follows:
@@
expression e;
@@
e = devm_pinctrl_register(...);
if(
- !e
+ IS_ERR(e)
)
{
<+...
return
- ...
+ PTR_ERR(e)
;
...+>
}
