Subject: [PATCH v2 14/39] drm/i915: document kernel-doc trivial issues
Date:   Wed, 13 Jul 2022 09:12:02 +0100
Message-Id: <6eca50ad78a54cadaf8e4deecec2309400c24164.1657699522.git.mchehab@kernel.org>

Fix those kernel-doc warnings:
	drivers/gpu/drm/i915/intel_region_ttm.c:199: warning: Function parameter or member 'offset' not described in 'intel_region_ttm_resource_alloc'
	drivers/gpu/drm/i915/i915_vma_resource.h:123: warning: Function parameter or member 'wakeref' not described in 'i915_vma_resource'
	drivers/gpu/drm/i915/i915_vma.c:1703: warning: Function parameter or member 'vma' not described in 'i915_vma_destroy_locked'
	drivers/gpu/drm/i915/i915_vma.c:751: warning: Function parameter or member 'ww' not described in 'i915_vma_insert'
	drivers/gpu/drm/i915/gt/uc/intel_guc_hwconfig.c:159: warning: Function parameter or member 'gt' not described in 'intel_gt_fini_hwconfig'
	drivers/gpu/drm/i915/gt/uc/intel_guc_hwconfig.c:146: warning: Function parameter or member 'gt' not described in 'intel_gt_init_hwconfig'
	drivers/gpu/drm/i915/gt/uc/intel_guc_hwconfig.c:113: warning: expecting prototype for intel_guc_hwconfig_init(). Prototype was for guc_hwconfig_init() instead
	drivers/gpu/drm/i915/gt/uc/intel_guc_hwconfig.c:113: warning: Function parameter or member 'gt' not described in 'guc_hwconfig_init'
	drivers/gpu/drm/i915/gt/intel_engine_types.h:276: warning: Function parameter or member 'preempt_hang' not described in 'intel_engine_execlists'

That are due undocumented parameters.
