Julia Lawall 9f9857bb5e drivers/net/wireless: introduce missing kfree 
Error handling code following a kzalloc should free the allocated data.

The semantic match that finds the problem is as follows:
(http://www.emn.fr/x-info/coccinelle/)

// <smpl>
@r exists@
local idexpression x;
statement S;
expression E;
identifier f,f1,l;
position p1,p2;
expression *ptr != NULL;

x@p1 = \(kmalloc\|kzalloc\|kcalloc\)(...);
...
if (x == NULL) S
<... when != x

print "* file: %s kmalloc %s return %s" % (p1[0].file,p1[0].line,p2[0].line)
