From ddf98e6d30a966dbd6e675c90e2caa5b9486e519 Mon Sep 17 00:00:00 2001 From: Thomas Meyer Date: Fri, 2 Dec 2011 12:35:43 +0000 Subject: [PATCH] ll_temac: Use kcalloc instead of kzalloc to allocate array The advantage of kcalloc is, that will prevent integer overflows which could result from the multiplication of number of elements and size and it is also a bit nicer to read.
