When debug_fence_init_onstack() is unused (CONFIG_DRM_I915_SELFTEST=n),
it prevents kernel builds with clang, `make W=1` and CONFIG_WERROR=y:
.../i915_sw_fence.c:97:20: error: unused function 'debug_fence_init_onstack' [-Werror,-Wunused-function]
97 | static inline void debug_fence_init_onstack(struct i915_sw_fence *fence)
| ^~~~~~~~~~~~~~~~~~~~~~~~
Fix this by marking debug_fence_init_onstack() with __maybe_unused.
See also commit 6863f5643d ("kbuild: allow Clang to find unused static
inline functions for W=1 build").

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.
