commit 18126c767658ae8a831257c6cb7776c5ba5e7249 upstream.
The following compilation error is false alarm as RDMA devices don't have such large amount of ports to actually cause to format truncation.
drivers/infiniband/core/cma_configfs.c: In function ‘make_cma_ports’: drivers/infiniband/core/cma_configfs.c:223:57: error: ‘snprintf’ output may be truncated before the last format character [-Werror=format-truncation=] 223 | snprintf(port_str, sizeof(port_str), "%u", i + 1); | ^ drivers/infiniband/core/cma_configfs.c:223:17: note: ‘snprintf’ output between 2 and 11 bytes into a destination of size 10 223 | snprintf(port_str, sizeof(port_str), "%u", i + 1); | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ cc1: all warnings being treated as errors make[5]: *** [scripts/Makefile.build:243: drivers/infiniband/core/cma_configfs.o] Error 1
