[PATCH] mlxsw: spectrum: mark symbols static where possible

Show all headers | View raw

We get 3 warnings when building kernel with W=1:
drivers/net/ethernet/mellanox/mlxsw/spectrum.c:251:29: warning: no previous prototype for 'mlxsw_sp_span_entry_find' [-Wmissing-prototypes]
drivers/net/ethernet/mellanox/mlxsw/spectrum.c:265:29: warning: no previous prototype for 'mlxsw_sp_span_entry_get' [-Wmissing-prototypes]
drivers/net/ethernet/mellanox/mlxsw/spectrum_router.c:1749:6: warning: no previous prototype for 'mlxsw_sp_fib_entry_put' [-Wmissing-prototypes]

In fact, these functions are only used in the file in which they are
declared and don't need a declaration, but can be made static.
so this patch marks these functions with 'static'.
