[ Upstream commitce52ec5bee] Commit1366a3db3d("staging: unisys: visorbus: visorchipset_init clean up gotos") assigns the initial value -ENODEV to the local variable 'err', and the first several error branches will return this value after "goto error". But commitf1f537c2e7("staging: unisys: visorbus: Consolidate controlvm channel creation.") overwrites 'err' in the middle of the way. As a result, some error branches do not successfully return the initial value -ENODEV of 'err', but return 0. In addition, when kzalloc() fails, -ENOMEM should be returned instead of -ENODEV. Fixes:f1f537c2e7("staging: unisys: visorbus: Consolidate controlvm channel creation.")

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.
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.
