dma-fence: add comment for WARN_ON in dma_fence_release() In dma_fence_release() there is a WARN_ON which could be triggered by several cases of wrong dma-fence usage. This patch adds a comment to explain two use-cases to help driver developers that use dma-fence and trigger that WARN_ON to better understand the reasons for it. v2: change to a more generic, one-liner comment Reviewed-by: Daniel Vetter <daniel.vetter@ffwll.ch> Signed-off-by: Oded Gabbay <oded.gabbay@gmail.com>
