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.
