RDMA/iwpm: Fix uninitialized error code in iwpm_send_mapinfo()
[ Upstream commit 302d6424e4a293a5761997e6c9fc3dfb1e4c355f ]
With gcc-4.1.2:
drivers/infiniband/core/iwpm_util.c: In function ‘iwpm_send_mapinfo’:
drivers/infiniband/core/iwpm_util.c:647: warning: ‘ret’ may be used uninitialized in this function
Indeed, if nl_client is not found in any of the scanned has buckets, ret
will be used uninitialized.
Preinitialize ret to -EINVAL to fix this.
Fixes: 30dc5e63d6a5ad24 ("RDMA/core: Add support for iWARP Port Mapper user space service")
