Subject: NTB: Multiple NTB client fix
From: Jon Mason <jon.mason@xxxxxxxxx>
commit 8b19d450ad188d402a183ff4a4d40f31c3916fbf upstream.
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.
