Hi, good catch, thanks!

I've added "Cc: stable at krnel.org [3.3+]" and pushed to l2-mtd.git,
thanks you.

But note, you should add your Signed-off-by when sending patches.
Also this patch is line-wrapped so I had to do a small surgery to apply
it. Try to save it from your mailbox and apply with 'git am'.

Anyway, thanks for the catch.
