dma-buf: Remove unused sync_dump()
sync_dump() is an unused, unexported, function that adds 64k to the kernel image and doesn't even provide locking around the global array it uses. add/remove: 0/2 grow/shrink: 0/0 up/down: 0/-65734 (-65734) Function old new delta sync_dump 198 - -198 sync_dump_buf 65536 - -65536 Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk> Cc: Sumit Semwal <sumit.semwal@linaro.org> Cc: Gustavo Padovan <gustavo@padovan.org> Reviewed-by: Daniel Vetter <daniel.vetter@ffwll.ch> Link: https://patchwork.freedesktop.org/patch/msgid/20190419181904.6199-1-chris@chris-wilson.co.uk
