After commit3392291fc5("drm/msm: Fix shrinker deadlock"), all supported versions of clang warn (or error with CONFIG_WERROR=y): drivers/gpu/drm/msm/msm_gem_shrinker.c:105:58: error: omitting the parameter name in a function definition is a C23 extension [-Werror,-Wc23-extensions] 105 | purge(struct drm_gem_object *obj, struct ww_acquire_ctx *) | ^ drivers/gpu/drm/msm/msm_gem_shrinker.c:117:58: error: omitting the parameter name in a function definition is a C23 extension [-Werror,-Wc23-extensions] 117 | evict(struct drm_gem_object *obj, struct ww_acquire_ctx *) | ^ 2 errors generated. With older but supported versions of GCC, this is an unconditional hard error: drivers/gpu/drm/msm/msm_gem_shrinker.c: In function 'purge': drivers/gpu/drm/msm/msm_gem_shrinker.c:105:35: error: parameter name omitted purge(struct drm_gem_object *obj, struct ww_acquire_ctx *) ^~~~~~~~~~~~~~~~~~~~~~~ drivers/gpu/drm/msm/msm_gem_shrinker.c: In function 'evict': drivers/gpu/drm/msm/msm_gem_shrinker.c:117:35: error: parameter name omitted evict(struct drm_gem_object *obj, struct ww_acquire_ctx *) ^~~~~~~~~~~~~~~~~~~~~~~ Restore the parameter name to clear up the warnings, renaming it "unused" to make it clear it is only needed to satisfy the prototype of drm_gem_lru_scan().
