We use delayed_work in HPD handling, and cancel any scheduled work in tfp410_fini using cancel_delayed_work_sync(). However, we have only initialized the delayed work if we actually have a HPD interrupt configured in the DT, but in the tfp410_fini, we always cancel the work, possibly causing a WARN(). Fix this by doing the cancel only if we actually had the delayed work set up.

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.
