From 3d9b1e53343651e514644f2a6d4ce00b362f4033 Mon Sep 17 00:00:00 2001 From: Markus Elfring Date: Fri, 25 Aug 2017 10:56:41 +0200 Subject: vme: ca91cx42: Improve 12 size determinations Replace the specification of data structures by variable references as the parameter for the operator "sizeof" to make the corresponding size determination a bit safer according to the Linux coding style convention.
