| H A D | lp3971.c | d662fc82 Sat Nov 21 15:18:44 CST 2009 Julia Lawall <julia@diku.dk> drivers/regulator: use PTR_ERR to get error code
IS_ERR returns only 1 or 0. The callsite of setup_regulators expects a
negative integer in an error case. Thus, PTR_ERR has to be used to extract
it.
The semantic match that finds this problem is as follows:
(http://coccinelle.lip6.fr/)
// <smpl>
@@
expression E,E1;
@@
*E = IS_ERR(...)
... when != E = E1
*return E;
// </smpl>
