Vadim Pasternak 36844c855b mlxsw: core: Add validation of hardware device types for MGPIR register 
When reading the number of gearboxes from the hardware, the driver does
not validate the returned 'device type' field. The driver can therefore
wrongly assume that the queried devices are gearboxes.

On Spectrum-3 systems that support different types of devices, this can
prevent the driver from loading, as it will try to query the
temperature sensors from devices which it assumes are gearboxes and in
fact are not.

For example:
[  218.129230] mlxsw_minimal 2-0048: Reg cmd access status failed (status=7(bad parameter))
[  218.138282] mlxsw_minimal 2-0048: Reg cmd access failed (reg_id=900a(mtmp),type=write)
[  218.147131] mlxsw_minimal 2-0048: Failed to setup temp sensor number 256
[  218.534480] mlxsw_minimal 2-0048: Fail to register core bus
[  218.540714] mlxsw_minimal: probe of 2-0048 failed with error -5

Fix this by validating the 'device type' field.

Fixes: f14f4e621b ("mlxsw: core: Extend thermal core with per inter-connect device thermal zones")

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.
