Title:
  [Hyper-V] vmbus: incorrect device name is printed when child device is
  unregistered

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  This issue impacts Ubuntu 12.04.

  Whenever a device is unregistered in vmbus_device_unregister
  (drivers/hv/vmbus_drv.c), the device name in the log message may
  contain garbage as the memory has already been freed by the time
  pr_info is called.  Log example:

    [ 3149.170475] hv_vmbus: child device àõsèè0_5 unregistered

  By logging the message just before calling device_unregister, the
  correct device name is printed:

    [ 3145.034652] hv_vmbus: child device vmbus_0_5 unregistered

  
  This issue has been resolved with the upstream patch: https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/drivers/hv/vmbus_drv.c?id=84672369ffb98a51d4ddf74c20a23636da3ad615
