commit6658a62e1dupstream. musb HWVers rgister address is not 0x69, if we operate the wrong address 0x69, it will cause a kernel crash, because there is no register corresponding to this address in the additional control register of musb. In fact, HWVers has been defined in musb_register.h, and the name is "MUSB_HWVERS", so We need to use this macro instead of 0x69.

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.
