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

Hi Roland,

Some coccinelle warnings are found:

drivers/infiniband/hw/ocrdma/ocrdma_verbs.c:895:6-54: duplicated argument to && or || drivers/infiniband/core/cma.c:3067:1-3: WARNING: PTR_RET can be used drivers/infiniband/core/ucma.c:1005:10-17: WARNING opportunity for memdep_user

And the 2nd one can be quieted by the attached patch :)
