Okay, I see. I think we're good for now, then -- hopefully anyone using
a UHS card on their laptop will see the printk when wondering why their
performance isn't great and get in touch with us, and we can investigate
more then.

I've pushed Manoj's patch to mmc-next for 3.1 now, with the printk
changes and a stable@ tag.


Thanks Chris!

Thanks again,

- Chris.
