From 1daef6d27b558d0bde72302ba7062b746887a643 Mon Sep 17 00:00:00 2001 From: Thomas Meyer Date: Tue, 29 May 2012 15:07:27 -0700 Subject: [PATCH] leds: 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.
