Jakub Kicinski 6ee2fdf2ba devlink: fix return value after hitting end in region read
[ Upstream commit 610a9346c138b9c2c93d38bf5f3728e74ae9cbd5 ]

Commit d5b90e99e1d5 ("devlink: report 0 after hitting end in region read")
fixed region dump, but region read still returns a spurious error:

$ devlink region read netdevsim/netdevsim1/dummy snapshot 0 addr 0 len 128

This is a minimal fix, I'll follow up with a restructuring
so we don't have two checks for the same condition.

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.
