Hi Ma, kernel test robot noticed the following build warnings: [auto build test WARNING on linus/master] [also build test WARNING on v6.7-rc4 next-20231207] [cannot apply to drm-misc/drm-misc-next wireless-next/main wireless/main] [If your patch is applied to the wrong git tree, kindly drop us a note.

During probe, call `acpi_amd_wbrf_supported_producer` to check if WBRF 60 can be enabled for the device. > 61 2. On using some frequency band, call `acpi_amd_wbrf_add_remove` with 'add' 62 param to get other consumers properly notified. 63 3. Or on stopping using some frequency band, call 64 `acpi_amd_wbrf_add_remove` with 'remove' param to get other consumers notified. 65 -- 0-DAY CI Kernel Test Service https://github.com/intel/lkp-tests/wiki
