Subject: [PATCH] drivers/atm/solos-pci.c: exchange pci_iounmaps

From: Julia Lawall <>

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: (

// <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
// </smpl>
