Yu-Chun Lin 1b0332a426 kthread: Fix return value on kzalloc() failure in kthread_affine_preferred()
kthread_affine_preferred() incorrectly returns 0 instead of -ENOMEM
when kzalloc() fails. Return 'ret' to ensure the correct error code is
propagated.

Fixes: 4d13f4304f ("kthread: Implement preferred affinity")

README

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 reStructuredText 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.
