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.

.. and sorry for the top post ..

Mikko


thanks,
Mikko

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'
