[ Upstream commit 5ffa828534036348fa90fb3079ccc0972d202c4a ]
The intent here was to return negative error codes but it actually
returns positive values. The problem is that type promotion with
ternary operations is quite complicated.
"ret" is an int. "copied" is a u32. And the snoop_file_read() function
returns long. What happens is that "ret" is cast to u32 and becomes
positive then it's cast to long and it's still positive.
Fix this by removing the ternary so that "ret" is type promoted directly
to long.
Fixes:

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.
