Hi,
I'm wondering what's the status of this patch?
if this has hit a subsystem tree yet? 0.75 watts power savings sounds really cool, but it doesn't seem to be in Linus's mainline yet. Has it hit a subsystem tree yet, or is there some issue that still needs to be resolved before it can go it?
Thanks, regards,
- Ted
