[ Upstream commit 6c7a388b62366f0de9936db3c1921d7f4e0011bc ]

Linking fails when dma-buf is disabled:

ld.lld: error: undefined symbol: dma_fence_release
>>> referenced by fence.c
>>>               gpu/host1x/fence.o:(host1x_syncpt_fence_enable_signaling) in archive drivers/built-in.a

>>> referenced by fence.c
>>>               gpu/host1x/fence.o:(do_fence_timeout) in archive drivers/built-in.a
