This driver currently assumes CONFIG_DMI is enabled along with ACPI. This may not be true. Due to this, the kernel test bot reports new warning like below for RISC-V allyesconfig builds. >> drivers/net/wireless/intel/iwlwifi/fw/acpi.c:1190:25: warning: '%s' directive argument is null [-Wformat-overflow=] 1190 | "System vendor '%s' is not in the approved list, disabling PPAG.\n", Fix the warnings by printing "<unknown>" when DMI interface returns NULL.
