Just to be clear, my post was in response to the reported problems with enabling sdio irqs with this patch: http://patchwork.kernel.org/patch/69122/ The patch originator reported good results but others reported complete failure. My hack fixed the problem for me. I believe this much more modest patch will also fix the problem but it is untested because I don't have a board running right now. Beware, I'm sending this from gmail so it may get line wrapped but it is a trivial patch so I think it is understandable.
