Aya Levin e26be26673 net/mlx5e: Fix crash in recovery flow without devlink reporter
commit 1ad6c43c6a7b8627240c6cc19c69e31fedc596a7 upstream.

When health reporters are not supported, recovery function is invoked
directly, not via devlink health reporters.

In this direct flow, the recover function input parameter was passed
incorrectly and is causing a kernel oops. This patch is fixing the input
parameter.

Following call trace is observed on rx error health reporting.

Internal error: Oops: 96000007 [#1] PREEMPT SMP
Process kworker/u16:4 (pid: 4584, stack limit = 0x00000000c9e45703)

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.
