From 8b19d450ad188d402a183ff4a4d40f31c3916fbf Mon Sep 17 00:00:00 2001 From: Jon Mason Date: Fri, 26 Apr 2013 14:51:57 -0700 Subject: [PATCH] NTB: Multiple NTB client fix Fix issue with adding multiple ntb client devices to the ntb virtual bus. Previously, multiple devices would be added with the same name, resulting in crashes. To get around this issue, add a unique number to the device when it is added.
