Title:
  chccwdev: Unexpected non-zero return code

Status in Ubuntu on IBM z Systems:
  Triaged
Status in s390-tools package in Ubuntu:
  New

Bug description:
  $ lsb_release -rd
  Description:	Ubuntu Yakkety Yak (development branch)
  Release:	16.10

  $ apt-cache policy s390-tools
  s390-tools:
    Installed: 1.36.1-0ubuntu2
    Candidate: 1.36.1-0ubuntu2
    Version table:
   *** 1.36.1-0ubuntu2 500
          500 http://us.ports.ubuntu.com/ubuntu-ports yakkety/main s390x Packages
          100 /var/lib/dpkg/status

  When benign options such as --help or --version are passed to chccwdev
  the expected output is printed but the return code is non-zero. This
  is inconsistent behaviour compared to other utilities shipped in the
  s390-tools package and a hindrance to dep8 autopkgtests tests. Please
  see LP bug 1616596 for further discussion as to why this can be an
  impact. The unexpected return code is shown here:

  $ chccwdev -h
  Usage: chccwdev [<options>] <devices>

  <options>
   	-a|--attribute <name>=<value>
   	-e|--online
   		Tries to set the given device online.
   	-f|--forceonline
   		Tries to force a device online if the device
   		driver supports this.
    	-d|--offline
    		Tries to set the given device offline.
    	-s|--safeoffline
    		Tries to set the given device offline waiting for all outstanding I/O. May block forever.
   	-v|--version
   		Show tools and command version.

  <devices>
   	<bus ID>[-<busid>][,<busid>[-<busid>]] ...
