Subject[PATCH 4/6] drivers/usb/host/ohci-nxp.c: adjust inconsistent IS_ERR and PTR_ERR
Date
From: Julia Lawall <Julia.Lawall@lip6.fr>

Change the call to PTR_ERR to access the value just tested by IS_ERR.

The semantic match that finds this problem is as follows:
(http://coccinelle.lip6.fr/)

// <smpl>
@@
expression e,e1;
@@

(
if (IS_ERR(e)) { ... PTR_ERR(e) ... }
|
if (IS_ERR(e=e1)) { ... PTR_ERR(e) ... }
|
*if (IS_ERR(e))
{ ...
* PTR_ERR(e1)
... }
)
// </smpl>
