From 0bebaa5f01bc018cd0246997d2b00f1ed44964a8 Mon Sep 17 00:00:00 2001 From: Markus Elfring Date: Thu, 13 Oct 2016 03:35:57 -0300 Subject: [PATCH] [media] RedRat3: Use kcalloc() in two functions * Multiplications for the size determination of memory allocations indicated that array data structures should be processed. Thus use the corresponding function "kcalloc". This issue was detected by using the Coccinelle software. * Replace the specification of data types by pointer dereferences to make the corresponding size determination a bit safer according to the Linux coding style convention.
