Eran Ben Elisha 88c8cf92db net/mlx5: Fix a bug of using ptp channel index as pin index 
On PTP mlx5_ptp_enable(on=0) flow, driver mistakenly used channel index
as pin index.

After ptp patch marked in fixes tag was introduced, driver can freely
call ptp_find_pin() as part of the .enable() callback.

Fix driver mlx5_ptp_enable(on=0) flow to always use ptp_find_pin(). With
that, Driver will use the correct pin index in mlx5_ptp_enable(on=0) flow.

In addition, when initializing the pins, always set channel to zero. As
all pins can be attached to all channels, let ptp_set_pinfunc() to move
them between the channels.

For stable branches, this fix to be applied only on kernels that includes
both patches in fixes tag. Otherwise, mlx5_ptp_enable(on=0) will be stuck
on pincfg_mux.

Fixes: 62582a7ee7 ("ptp: Avoid deadlocks in the programmable pin code.")
Fixes: ee7f12205a ("net/mlx5e: Implement 1PPS support")

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 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.
