[PATCH] mfd: omap-usb-host: Make TLL mode work again

[Anand Gadiyar]

This code section seems to have been accidentally copy pasted.
It causes incorrect bits to be set up in the TLL_CHANNEL_CONF
register and prevents the TLL mode from working correctly.

Against v3.1-rc2; tested against linux-next as of 20110817 as well.

This probably needs to go to -stable as well. The original code
by me worked fine but this was broken during the code reorganization
Keshava did.

Sam, you can apply this one:

Acked-by: Felipe Balbi <balbi@ti.com>

But I think it needs to be resent with Cc: stable@kernel.org

I'm trying to avoid "Cc: stable@kernel.org" since RMK complained about
this on the Linux ARM kernel list. [1]

Why would he do that?  You need to put the Cc: in the signed off by
area, and all will be fine.  If you just put it in your email, you will
get an automated email from me telling you to go read
Documentation/stable_kernel_rules.txt which tells you exactly how to do
this properly.
