With the addition of the DMA fence, the host1x driver now fails to
build without the sync_file helper:
arm-linux-gnueabi-ld: drivers/gpu/host1x/fence.o: in function `host1x_fence_create_fd':
fence.c:(.text+0x624): undefined reference to `sync_file_create'
Fixes: ad0529424def ("gpu: host1x: Add DMA fence implementation")

Hi Arnd,
I think the best fix for this is to just remove that function -- it is
currently not used anywhere. I posted a patch to do that, but Thierry is
currently on vacation so it hasn't been picked up yet.
thanks,
Mikko
