Subject: [PATCH 0/2] Drivers: hv: vmbus: make bus ids in sysfs persistent

Bus ids for VMBus devices in /sys/bus/vmbus/devices/ are not guaranteed
to be persistent across reboot or kernel restart and this causes problems
for some tools. E.g. kexec tools use these ids to identify NIC on kdump.
Fix the issue by using relid from channel offer as the unique id instead
of an auto incremented counter.

  Drivers: hv: make VMBus bus ids persistent
  Drivers: hv: get rid of id in struct vmbus_channel
