Simple questions first: - why do you have 3 different .h files for a single .c file? - why do you have any public .h files for a single .c file? - use the correct SPDX markers for your file licenses, Intel legal knows all about this, please follow their rules. - why is this in a subdirectory for a single .c file? thanks, greg k-h
