From 246740656a37495c7a0b87c7dcfbb9b5d9bae9fd Mon Sep 17 00:00:00 2001 From: Markus Elfring Date: Fri, 25 Aug 2017 09:46:13 +0200 Subject: [PATCH] vme: fake: Improve five size determinations in fake_init() Replace the specification of data structures by pointer dereferences as the parameter for the operator "sizeof" to make the corresponding size determination a bit safer according to the Linux coding style convention. This issue was detected by using the Coccinelle software.
