Did I nack this patch and not realize it?

Does my patch fix the warning for pxaficp_ir that would still be emitted
with this patch? If the driver uses GFP_DMA and nobody from the arm side
is prepared to remove it yet, then I'd suggest merging my patch until that
can be determined. Otherwise, you have no guarantees about where the
memory is actually coming from.
