[PATCH] drivers/atm/solos-pci.c: exchange pci_iounmaps
From: Julia Lawall
Date: Sun Feb 19 2012 - 14:43:39 EST
From: Julia Lawall <Julia.Lawall@xxxxxxx>
The calls to pci_iounmap are in the wrong order, as compared to the
associated calls to pci_iomap.
A simplified version of the semantic match that finds this problem is as
follows: (http://coccinelle.lip6.fr/)
// <smpl>
@@
expression e,x;
statement S,S1;
int ret;
@@
e = pci_iomap(x,...)
... when != pci_iounmap(x,e)
if (<+...e...+>) S
... when any
when != pci_iounmap(x,e)
*if (...)
{ ... when != pci_iounmap(x,e)
return ...; }
... when any
pci_iounmap(x,e);
// </smpl>
