From 3382576106014bf865d341efab3d94fb28d1fc63 Mon Sep 17 00:00:00 2001 From: Karsten Graul Date: Thu, 26 Apr 2018 17:18:20 +0200 Subject: net/smc: fix structure size The struct smc_cdc_msg must be defined as packed so the size is 44 bytes. And change the structure size check so sizeof is checked. Signed-off-by: Karsten Graul Signed-off-by: Ursula Braun Signed-off-by: David S.
