[59/89] drivers/usb/host/ehci-fsl.c: add missing iounmap
From: Greg KH
Date: Wed Feb 01 2012 - 16:19:54 EST
3.2-stable review patch. If anyone has any objections, please let me know.
------------------
From: Julia Lawall <Julia.Lawall@xxxxxxx>
commit 2492c6e6454ff3edb11e273b071a6ea80a199c71 upstream.
Add missing iounmap in error handling code, in a case where the function
already preforms iounmap on some other execution path.
A simplified version of the semantic match that finds this problem is as
follows: (http://coccinelle.lip6.fr/)
// <smpl>
@@
expression e;
statement S,S1;
int ret;
@@
e = \(ioremap\|ioremap_nocache\)(...)
... when != iounmap(e)
if (<+...e...+>) S
... when any
when != iounmap(e)
*if (...)
{ ... when != iounmap(e)
return ...; }
... when any
iounmap(e);
// </smpl>
