Some configurations produce this harmless warning when built with gcc -Wmaybe-uninitialized: infiniband/core/cma.c: In function 'cma_get_net_dev': infiniband/core/cma.c:1242:12: warning: 'src_addr_storage.sin_addr.s_addr' may be used uninitialized in this function [-Wmaybe-uninitialized] I previously reported this for the powerpc64 defconfig, but have now reproduced the same thing for x86 as well, using gcc-5 or higher. The code looks correct to me, and this change just rearranges it by making sure we alway initialize the entire address structure to make the warning disappear. My first approach added an initialization at the time of the declaration, which Doug commented may be too costly, so I hope this version doesn't add overhead.
