Julia Lawall a4b1164961 drivers/net/phy: 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
     when != if (...) { <+...x...+> }

 f(...,x->f1,...)
)

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