The sparse tool complains as follows: drivers/usb/host/xhci-dbgtty.c:401:5: warning: symbol 'xhci_dbc_tty_register_device' was not declared. Should it be static? drivers/usb/host/xhci-dbgtty.c:452:6: warning: symbol 'xhci_dbc_tty_unregister_device' was not declared. Should it be static? After commit6ae6470bfa("xhci: dbc: Add a operations structure to access driver functions"), those functions are not used outside of xhci-dbgtty.c, so this commit marks them static.

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.
