When device_add(&udev->dev) succeeds and a later call fails,
usb_new_device() does not properly call device_del(). As comment of
device_add() says, 'if device_add() succeeds, you should call
device_del() when you want to get rid of it. If device_add() has not
succeeded, use only put_device() to drop the reference count'.

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 reStructuredText 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.
