Use flush_work() instead of cancel_work_sync() for driver IRQ
workqueues to guarantee that remaining pending work
will be handled.
This resolves two issues that were encountered where a driver was left
in an incorrect state as the bottom-half was canceled:
1. Cancelling context-abort of a job that is still executing and
is causing translation faults which is going to cause additional TDRs
2. Cancelling bottom-half of a DCT (duty-cycle throttling) request
which will cause a device to not be adjusted to an external frequency
request.

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.
