From: Thomas Meyer <thomas@m3y3r.de>
Casting (void *) value returned by kmalloc is useless as mentioned in Documentation/CodingStyle, Chap 14.
The semantic patch that makes this output is available in scripts/coccinelle/api/alloc/drop_kmalloc_cast.cocci.
More information about semantic patching is available at http://coccinelle.lip6.fr/
