infiniband build warning

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.

A program is never fully debugged until the last user dies.

A patch to fix this was submitted to the linux-rdma list last week. Thanks.

Hi Roland,

There is a nice set of patches (IPoIB virtualization fixes, mlx5 fixes, iser patches to cope with Connect-IB no FMR, etc, etc) posted to linux-rdma little before && after 3.11-rc1 was out, and we are @ rc2 now. I think we need to get them upstreamed around this time such that its early enough in the cycle, makes sense?

Or.
