dma-fence: Silence sparse warning in dma_fence_describe
Sparse complains about assigning a string to a __rcu annotated local
variable:
drivers/dma-buf/dma-fence.c:1040:38: warning: incorrect type in initializer (different address spaces)
drivers/dma-buf/dma-fence.c:1040:38: expected char const [noderef] __rcu *timeline
drivers/dma-buf/dma-fence.c:1040:38: got char *
drivers/dma-buf/dma-fence.c:1041:36: warning: incorrect type in initializer (different address spaces)
drivers/dma-buf/dma-fence.c:1041:36: expected char const [noderef] __rcu *driver
drivers/dma-buf/dma-fence.c:1041:36: got char *
It is harmless but lets silence it.
