2012-05-08RDMA/ocrdma: Set event's device member in ocrdma_dispatch_ibevent()Roland Dreier1-1/+3
We need to set ib_evt.device, or else ib_dispatch_event() will crash when we call it for unaffiliated events (and consumers may get confused in their QP/CQ/SRQ event handler for affiliated events). Also fix sparse warning: drivers/infiniband/hw/ocrdma/ocrdma_hw.c:678:36: warning: Using plain integer as NULL pointer There's no need to clear ib_evt, since every member is initialized.

2012-05-08RDMA/ocrdma: Make needlessly global functions/structs staticRoland Dreier1-6/+6
Signed-off-by: Roland Dreier <roland@purestorage.com>
2012-05-08RDMA/ocrdma: Fix warnings about uninitialized variablesRoland Dreier1-1/+1
First, fix drivers/infiniband/hw/ocrdma/ocrdma_verbs.c: In function 'ocrdma_alloc_pd': drivers/infiniband/hw/ocrdma/ocrdma_verbs.c:371:17: warning: 'dpp_page_addr' may be used uninitialized in this function [-Wuninitialized] drivers/infiniband/hw/ocrdma/ocrdma_verbs.c:337:6: note: 'dpp_page_addr' was declared here which seems that it may border on a bug (the call to ocrdma_del_mmap() might conceivably do bad things if pd->dpp_enabled is not set and dpp_page_addr ends up with just the wrong value). Also take care of: drivers/infiniband/hw/ocrdma/ocrdma_hw.c: In function 'ocrdma_init_hw': drivers/infiniband/hw/ocrdma/ocrdma_hw.c:2587:5: warning: 'status' may be used uninitialized in this function [-Wuninitialized] drivers/infiniband/hw/ocrdma/ocrdma_hw.c:2549:17: note: 'status' was declared here which is only real if num_eq == 0, which should be impossible.
