The user of this function passes a pointer to a value that doesn't exist when compiled w/o CONFIG_ACPI. Since we don't need the value then, make the non-ACPI version a macro to allow it to still build. Reported-by: kernel test robot <lkp@intel.com> Closes: https://lore.kernel.org/oe-kbuild-all/202402031454.syX4cSGN-lkp@intel.com/ Fixes: c4c954547755 ("wifi: iwlwifi: implement WPFC ACPI table loading") Signed-off-by: Johannes Berg <johannes.berg@intel.com>
