From bb2a600c72959187bd254172945d4aa9875252f9 Mon Sep 17 00:00:00 2001 From: Thomas Meyer Date: Thu, 3 May 2012 15:44:25 +1000 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.
