commit fc6bcf9ac4de76f5e7bcd020b3c0a86faff3f2d5 upstream.
Patch series "powerpc/pseries/cmm: two smaller fixes".
Two smaller fixes identified while doing a bigger rework.
This patch (of 2):
We always have to initialize the balloon_dev_info, even when compaction is
not configured in: otherwise the containing list and the lock are left
uninitialized.
Likely not many such configs exist in practice, but let's CC stable to
be sure.
This was found by code inspection.

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.
