Date: Mon, 30 May 2011 09:22:51 +0200 From: Sven Eckelmann <sven@...fation.org> To: davem@...emloft.net Cc: netdev@...r.kernel.org, b.a.t.m.a.n@...ts.open-mesh.org, Sven Eckelmann <sven@...fation.org> Subject: [PATCH 06/17] batman-adv: Don't do pointer arithmetic with void* The size of void is currently set by gcc to 1, but is not well defined in general. Therefore it is more advisable to cast it to char* before doing pointer arithmetic.
