The "unode" pointer cannot be NULL here and checking for it causes
Smatch warnings:
drivers/gpu/drm/udl/udl_main.c:259 udl_get_urb_locked()
warn: can 'unode' even be NULL?
Fortunately, it's just harmless dead code which can be removed. It's
left over from commit c5c354a3a4 ("drm/udl: Fix inconsistent urbs.count
value during udl_free_urb_list()").

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.
