drivers/iio/adc/at91_adc.c: adjust inconsistent IS_ERR and PTR_ERR
Author: 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/)
//
@@
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)
... }
)
//
