This patch adds a dev_dbg() message to usb_create_sysfs_intf_files(). The message is not expected ever to appear; it's real purpose is to satisfy the __must_check attribute on device_create_file() without triggering a compiler warning about an empty statement. In fact we don't really care if the sysfs attribute file doesn't get created. The interface string descriptor is purely informational and hardly ever present.

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.
