You are right that's technically not needed, but rather I was following
how other prototypes are defined in that header file (like the ones that
get declared when CONFIG_ANDROID_BOOT_IMAGE is defined).

For now I'm not planning to re-spin the patch series, but if there is
additional feedback I can take care of this one as well.

Thanks and Regards,
