Yes, this is correct. The substance of the change is simply to use the
leds-gpio interface rather than fiddling with gpio settings directly.
However, please note that Grant and Andres suggested that the driver
should instead move to "arch" and out of leds? Therefore, I created an
updated version of this patch which you can find from message id:
"1300553466-23873-1-git-send-email-kernel@wildgooses.com", ie:
http://lists.zerezo.com/linux-kernel/msg27455553.html

Additionally this updated patch has a slightly amended copyright -
several folks thought that the updated copyright statement was more
appropriate

My apologies that this updated patch was not more clearly marked as such
- Grant has taken the time to point out how I should submit patches more
clearly in the future

I would be happy to shuffle the code around further if anyone has an
opinion?

Thanks for picking this up

Ed W
