[PATCH] dma-fence: use correct callback in dma_fence_timeline_name()

From: André Draszik

Date: Thu Jun 18 2026 - 08:01:11 EST


dma_fence_timeline_name() is a wrapper around
dma_fence_ops::get_timeline_name(). Since the blamed commit below, it
calls an incorrect callback.

Update it to restore functionality by calling the intended callback.
