[ Upstream commita5e63c7d38] The logic for discerning between KSZ8051 and KSZ87XX PHYs is incorrect such that the that KSZ87XX switch is not identified correctly. ksz8051_ksz8795_match_phy_device() uses the parameter ksz_phy_id to discriminate whether it was called from ksz8051_match_phy_device() or from ksz8795_match_phy_device() but since PHY_ID_KSZ87XX is the same value as PHY_ID_KSZ8051, this doesn't work. Instead use a bool to discriminate the caller. Without this patch, the KSZ8795 switch port identifies as: ksz8795-switch spi3.1 ade1 (uninitialized): PHY [dsa-0.1:03] driver [Generic PHY] With the patch, it identifies correctly: ksz8795-switch spi3.1 ade1 (uninitialized): PHY [dsa-0.1:03] driver [Micrel KSZ87XX Switch] Fixes:8b95599c55("net: phy: micrel: Discern KSZ8051 and KSZ8795 PHYs") Signed-off-by: Steve Bennett <steveb@workware.net.au> Reviewed-by: Marek Vasut <marex@denx.de> Signed-off-by: David S.

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.
