If CONFIG_NET_HWBM is not set, then these stub functions in <net/hwbm.h> should be declared static to avoid trying to export them from any driver that includes this. Fixes the following sparse warnings: ./include/net/hwbm.h:24:6: warning: symbol 'hwbm_buf_free' was not declared. Should it be static? ./include/net/hwbm.h:25:5: warning: symbol 'hwbm_pool_refill' was not declared. Should it be static? ./include/net/hwbm.h:26:5: warning: symbol 'hwbm_pool_add' was not declared. Should it be static? Signed-off-by: Ben Dooks (Codethink) <ben.dooks@codethink.co.uk> Signed-off-by: David S. Miller <davem@davemloft.net>
