9e8fa040cb RDMA/ocrdma: Fix check of GSI CQs
It looks like one check was accidentally duplicated, and the other 3
checks were left out.  This was detected by scripts/coccinelle/tests/doubletest.cocci:

    drivers/infiniband/hw/ocrdma/ocrdma_verbs.c:895:6-54: duplicated argument to && or ||

7b33dc2b05 RDMA/ocrdma: Fix off by one in ocrdma_query_gid()
The dev->sgid_tbl[] array is allocated in ocrdma_alloc_resources().
It has OCRDMA_MAX_SGID elements so the test here is off by one.

da4964387d RDMA/ocrdma: Fix warnings about uninitialized variables
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.
