[ Upstream commit 0097ae5f7af5684f961a5f803ff7ad3e6f933668 ] When the function IS_ALIGNED() returns false, the value of ret is 0. So, we set ret to -EINVAL to indicate this error. Clean up smatch warning: drivers/ntb/test/ntb_perf.c:602 perf_setup_inbuf() warn: missing error code 'ret'.

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.
