Julia Lawall bc111d570b drivers/atm: introduce missing kfree 
Error handling code following a kmalloc 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,l;
position p1,p2;
expression *ptr != NULL;

)
<... when != x
     when != if (...) { <+...x...+> }
