pinctrl: digicolor: convert null test to IS_ERR test
Since commit 323de9efdf3e ("pinctrl: make pinctrl_register() return proper
error code"), pinctrl_register returns an error code rather than NULL on
failure. Update a driver that was introduced more recently.
The semantic patch that makes this change is as follows:
(http://coccinelle.lip6.fr/)
// <smpl>
@@
expression e,e1,e2;
@@
e = pinctrl_register(...)
... when != e = e1
if (
- e == NULL
+ IS_ERR(e)
) {
...
return
- e2
+ PTR_ERR(e)
;
}
// </smpl>
