Subject: [PATCH] sctp: dont cast void* from kmalloc()
Date: Sat, 13 Aug 2011 11:43:45 +0200 [thread overview]
Message-ID: <1313228625.16820.42.camel@localhost.localdomain> (raw)
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/
