Subject: [PATCH v2] wifi: iwlwifi: Fix build warning when DMI is not enabled
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.
Reported-by: kernel test robot <lkp@...el.com>
Closes: https://lore.kernel.org/oe-kbuild-all/202311040602.sCjU3UXr-lkp@intel.com/

Changes since v1:
1) Modified the fix not to add dependency on DMI in Kconfig as
per feedback from Johannes.
