Selvarasu Ganesan e589ee5dcc usb: dwc3: Move GUID programming after PHY initialization
[ Upstream commit aad35f9c92 ]

The Linux Version Code is currently written to the GUID register before
PHY initialization. Certain PHY implementations (such as Synopsys eUSB
PHY performing link_sw_reset) clear the GUID register to its default
value during initialization, causing the kernel version information to
be lost.

Move the GUID register programming to occur after PHY initialization
completes to ensure the Linux version information persists.

Fixes: fa0ea13e9f ("usb: dwc3: core: write LINUX_VERSION_CODE to our GUID register")

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.
