The smatch warns about uncleaned resources in case the
parport_register_port() fails:
parport_register_port() warn: '&tmp->full_list' not removed from list
This is indeed an issue introduced when converting code to use
kasprintf(). However, the whole kasprintf() dance in this case
is not needed as dev_set_name() can handle the formatted input
and produces the same result. So, the solution is to delegate
name forming to the dev_set_name() and make device_register()
error path to deal with error handling (via put_device() call).

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.
