Rather check if the engine is still registered before proceeding with deregister steps. Also the engine being marked as disabled doesn't mean the engine has been disabled or deregistered from GuC pov, and here we are signalling fences so we need to be sure GuC is not still using this context. v2: - Drop the read_stopped() for this path. Since we are signalling fences on error here, best play it safe and wait for the GT reset to mark the engine as disabled, rather than it just being queued. v3 (Matt Brost): - Keep the read_stopped() on the wait event, since there is no need to wait for an already scheduled GT reset. If it is set we can then just bail without signalling anything.

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.
