Thanks applying into fixes.

I've dropped this last line as that's pretty obvious from the commit alone.
You can put extra comments like that could between some "---" lines:
---
This is based on -rc4...
---
So they get ignored when the patch gets applied. What is important,
is what it was tested on, so saying "Tested on ams delta" would be
more meaningful, although I guess that too is pretty obvious in this
case :)

Regards,

Tony

Hi Tony,
Thanks for taking this patch, but I ca't see it applied into your fixes
branch (the last one sitting there is "Linux 3.4-rc4" by Linus). Am I
missing something?

Janusz

Oops, sorry forgot to push it out. Pushed out now, so it should appear
on the mirrors shortly.
