We have already few similar implementation and a lot of code that can benefit of the yesno() helper. Consolidate yesno() helpers under string.h hood.
I was taking a look on i915_utils.h to reduce it and move some of it elsewhere to be shared with others. I was starting with these helpers and had [1] done, then Jani pointed me to this thread and also his previous tentative. I thought the natural place for this would be include/linux/string_helpers.h, but I will leave it up to you. After reading the threads, I don't see real opposition to it. Is there a tree you plan to take this through? thanks Lucas De Marchi [1] https://lore.kernel.org/lkml/20211005212634.3223113-1-lucas.demarchi@intel.com/T/#u (local)
