Building with W=1 reports a -Wformat-truncation warning on niu_set_irq_name(): the "%s:SYSERR" format could be truncated because irq_name[] was one byte too small for the worst case interface name length (IFNAMSIZ-1) plus the ":SYSERR" suffix. Increase the irq_name buffer size to account for the suffix and replace the remaining sprintf() calls in the same function with snprintf() to avoid possible buffer overflows. Tested: - Built the kernel with W=1 and confirmed the warning is no longer reported. - No NIU hardware was available for runtime testing.
