A failure in xe_force_wake_get() no longer increments the domain's refcount. Therefore, if xe_force_wake_get() fails during forcewake debugfs open, return an error. This ensures there are no valid file descriptors to close via forcewake debugfs, preventing refcount mismanagement. v3 - return xe_wakeref_t instead of int in xe_force_wake_get() v5 - return unsigned int from xe_force_wake_get() v6 - Use helper xe_force_wake_ref_has_domain() to determine the status of the call.

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.
