RDMA/siw: Mark expected switch fall-throughs
In preparation to enabling -Wimplicit-fallthrough, mark switch cases where we are expecting to fall through. This patch fixes the following warnings: drivers/infiniband/sw/siw/siw_qp_rx.c: In function ‘siw_rdmap_complete’: drivers/infiniband/sw/siw/siw_qp_rx.c:1214:18: warning: this statement may fall through [-Wimplicit-fallthrough=] wqe->rqe.flags |= SIW_WQE_SOLICITED; ~~~~~~~~~~~~~~~^~~~~~~~~~~~~~~~~~~~ drivers/infiniband/sw/siw/siw_qp_rx.c:1215:2: note: here case RDMAP_SEND: ^~~~ drivers/infiniband/sw/siw/siw_qp_tx.c: In function ‘siw_qp_sq_process’: drivers/infiniband/sw/siw/siw_qp_tx.c:1044:4: warning: this statement may fall through [-Wimplicit-fallthrough=] siw_wqe_put_mem(wqe, tx_type); ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~ drivers/infiniband/sw/siw/siw_qp_tx.c:1045:3: note: here case SIW_OP_INVAL_STAG: ^~~~ drivers/infiniband/sw/siw/siw_qp_tx.c:1128:4: warning: this statement may fall through [-Wimplicit-fallthrough=] siw_wqe_put_mem(wqe, tx_type); ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~ drivers/infiniband/sw/siw/siw_qp_tx.c:1129:3: note: here case SIW_OP_INVAL_STAG: ^~~~ Warning level 3 was used: -Wimplicit-fallthrough=3 This patch is part of the ongoing efforts to enable -Wimplicit-fallthrough.
