Subject[PATCH] sctp: dont cast void* from kmalloc()
From
Date
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/
