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.
