Hi,
I am seeing build warnings in drivers/infiniband/core/cma.c starting with
v3.11-rc1. These can be reproduced with gcc 4.6.3.
Would you consider applying the following fix ?
(The compiler warning seems benign as I could easily convince myself that the
variable won't be used uninitialized, but I'd like to get rid of the compiler
warning anyway).

infiniband: fix maybe-uninitialized warning in rdma_resolve_addr()
This fixes the following warning:
drivers/infiniband/core/cma.c: In function 'rdma_resolve_addr':
drivers/infiniband/core/cma.c:465:23: error: 'port' may be used uninitialized
in this function [-Werror=maybe-uninitialized]
drivers/infiniband/core/cma.c:426:5: note: 'port' was declared here
The warning looks benign: port is only used after checking that
cma_dev is not NULL, and all assignments to cma_dev also set port.
