    CONFIG_PM=n:

    drivers/base/firmware_class.c:1147: warning: 'device_cache_fw_images' defined but not used
    drivers/base/firmware_class.c:1212: warning: 'device_uncache_fw_images_delay' defined but not used

    the fix is not trivial - this patch added quite a lot of code and data
    structure bloat which will never be used on CONFIG_PM=n kernels.


    (Well, a trivial fix would be to eradicate CONFIG_PM=n, but...)
