drm/i915/fence: Mark debug_fence_free() with __maybe_unused
[ Upstream commit f99999536128b14b5d765a9982763b5134efdd79 ]
When debug_fence_free() is unused
(CONFIG_DRM_I915_SW_FENCE_DEBUG_OBJECTS=n), it prevents kernel builds
with clang, `make W=1` and CONFIG_WERROR=y:
.../i915_sw_fence.c:118:20: error: unused function 'debug_fence_free' [-Werror,-Wunused-function]
118 | static inline void debug_fence_free(struct i915_sw_fence *fence)
| ^~~~~~~~~~~~~~~~
Fix this by marking debug_fence_free() with __maybe_unused.
See also commit 6863f5643dd7 ("kbuild: allow Clang to find unused static
inline functions for W=1 build").
Fixes: fc1584059d6c ("drm/i915: Integrate i915_sw_fence with debugobjects")
