[PATCH 6/6] drivers/iio/adc/at91_adc.c: adjust inconsistent IS_ERR and PTR_ERR

From: Julia Lawall
Date: Sat Aug 25 2012 - 15:58:26 EST


From: Julia Lawall <Julia.Lawall@xxxxxxx>

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>
