From e79c70e6e59e764fbef2a68a7d7303c3286ea7a8 Mon Sep 17 00:00:00 2001 From: Thomas Meyer Date: Tue, 29 Nov 2011 17:08:00 -0300 Subject: [PATCH] [media] pvrusb2: 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.
