[ Upstream commitb5130dc222] When running as a level 3 guest with no host provided sthyi support sclp_ocf_cpc_name_copy() will only return zeroes. Zeroes are not a valid group name, so let's not indicate that the group name field is valid. Also the group name is not dependent on stsi, let's not return based on stsi before setting it.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
See Documentation/00-INDEX for a list of what is contained in each file.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
