Subject: [PATCH v6 13/20] drm/i915/vm_bind: Update i915_vma_verify_bind_complete()
Date: Mon, 7 Nov 2022 00:52:03 -0800 [thread overview]
Message-ID: <20221107085210.17221-14-niranjana.vishwanathapura@intel.com> (raw)
In-Reply-To: <20221107085210.17221-1-niranjana.vishwanathapura@intel.com>
Ensure i915_vma_verify_bind_complete() handles case where bind
is not initiated. Also make it non static, add documentation
and move it out of CONFIG_DRM_I915_DEBUG_GEM.
v2: Fix fence leak
