From d5cf467ecec5a3924a602018c6e405ad6d0dbecc Mon Sep 17 00:00:00 2001 From: Markus Elfring Date: Wed, 12 Oct 2016 10:30:44 -0300 Subject: [media] DaVinci-VPIF-Display: Use kcalloc() in vpif_probe() * A multiplication for the size determination of a memory allocation indicated that an array data structure should be processed. Thus use the corresponding function "kcalloc". This issue was detected by using the Coccinelle software. * Replace the specification of a data type by a pointer dereference to make the corresponding size determination a bit safer according to the Linux coding style convention.
