From fc20b5809dbc7ee8a341ec5db166de5a51d7118a Mon Sep 17 00:00:00 2001 From: Stephen Hemminger Date: Thu, 7 Feb 2019 19:44:01 -0800 Subject: [PATCH] bus/vmbus: fix secondary process setup The secondary process doesn't correctly map the second and later resources because it doesn't change the offset.
