The delayed_work delayed_work_enable_hotplug is initialized with
INIT_DELAYED_WORK() in adv7842_probe(), but it is never scheduled
anywhere in the probe function.
Calling cancel_delayed_work() on a work that has never been
scheduled is redundant and unnecessary, as there is no pending
work to cancel.
Remove the redundant cancel_delayed_work() from error handling
path and adjust the goto label accordingly to simplify the code
and avoid potential confusion.

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.
