From: Julia Lawall <julia at diku.dk>
At this point, the ioremap has taken place, so the error handling code at
the label err_iounmap should be used rather than returning directly.
The semantic match that finds this problem is as follows:
(http://coccinelle.lip6.fr/)
// <smpl>
@r@
identifier x;
@@
kfree(x)
@@
identifier r.x;
expression E1!=0,E2,E3,E4;
statement S;
@@
(
if (<+...x...+>) S
|
if (...) { ... when != kfree(x)
when != if (...) { ... kfree(x); ... }
when != x = E3
* return E1;
}
... when != x = E2
if (...) { ... when != x = E4
kfree(x); ... return ...; }
)
// </smpl>
