commit 8eb37ab7cc045ec6305a6a1a9c32374695a1a977 upstream.
Issue seen when enumerating multiple Intel mGbE interfaces in EHL.
[ 6.898141] intel-eth-pci 0000:00:1d.2: enabling device (0000 -> 0002)
[ 6.900971] intel-eth-pci 0000:00:1d.2: Fail to register stmmac-clk
[ 6.906434] intel-eth-pci 0000:00:1d.2: User ID: 0x51, Synopsys ID: 0x52
We fix it by making the clock name to be unique following the format
of stmmac-pci_name(pci_dev) so that we can differentiate the clock for
these Intel mGbE interfaces in EHL platform as follow:
/sys/kernel/debug/clk/stmmac-0000:00:1d.1
/sys/kernel/debug/clk/stmmac-0000:00:1d.2
/sys/kernel/debug/clk/stmmac-0000:00:1e.4
Fixes: 58da0cfa6cf1 ("net: stmmac: create dwmac-intel.c to contain all Intel platform")

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.
