Subject: drivers/usb/host/ohci-nxp.c: adjust inconsistent IS_ERR and PTR_ERR
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=2ec15a6fbe931a8e0b45a3b26f59b9eb2701b4d1;p=openwrt%2Fstaging%2Fblogic.git

drivers/usb/host/ohci-nxp.c: adjust inconsistent IS_ERR and PTR_ERR

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>
