From a451eaf9c57feaacfd76226a06bd57c4b66a6ab3 Mon Sep 17 00:00:00 2001 From: Thomas Meyer Date: Tue, 29 Nov 2011 22:08:00 +0100 Subject: [PATCH] uwb: 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.
