drivers/net/wireless/mwifiex/scan.c: test the just-initialized value
Test the just-initialized value rather than some other one.
The semantic match that finds this problem is as follows:
(http://coccinelle.lip6.fr/)
// <smpl>
@r@
identifier x,y,f!={PTR_ERR,ERR_PTR,ERR_CAST};
statement S;
@@
x = f(...);
(
if (\(x == NULL\|IS_ERR(x)\)) S
|
*if (\(y == NULL\|IS_ERR(y)\))
{ ... when != x
return ...; }
)
// </smpl>
