Why would I care? If your config wakeups up so often that you need special casing find a way to deal with it.
You should care, because the change you're suggesting might break code that I maintain. If you don't care about breaking my code with your change, than just have my "nack", and it'll be up to Greg to decide whether he wants to apply this despite the nack for two separate affected code spots.
On the technical topic, an Android developer friend following this thread just pointed out to me that Android doesn't use PM_AUTOSLEEP and just has userspace causing suspend frequently. So by his rough estimation your patch actually *will* break Android devices. Zoinks. Maybe he's right, maybe he's not -- I don't know -- but you should probably look into this if you want this patch to land without breakage.
