We get 1 warning when building kernel with W=1: drivers/dma-buf/sw_sync.c:87:23: warning: no previous prototype for 'sync_timeline_create' [-Wmissing-prototypes]
In fact, this function is only used in the file in which it is declared and don't need a declaration, but can be made static. So this patch marks it 'static'.
