[Acked] [PATCH] [Natty SRU - both master and ti-omap4] Fix usb on omap hw when gcc 4.6 is used

[Bryan Wu]

Andy and Tim,

I was pinged by Adam for this EHCI fixing patch, which is very
important for Oneiric kernel of ti-omap4, because we are still using
Natty kernel for our Oneiric image.

Would you please upload Natty ti-omap4 kernel? This is patch is in our
repo but not upload yet. I think we need this for our A2 image
testing.

Thanks,
-Bryan
