From: Thomas Meyer
Date: Sat Aug 13 2011 - 10:12:58 EST

From: Thomas Meyer <thomas@xxxxxxxx>

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
