My patch is basically the same, just with the field renamed too, and
not blindly just assigning to "*pdev->dev.dma_mask" (my variant does

        pdev->platform_dma_mask = pdevinfo->dma_mask;
        pdev->dev.dma_mask = &pdev->platform_dma_mask;

instead of that incomprehensible

        *pdev->dev.dma_mask = pdevinfo->dma_mask;

which depends on that dev.dma_mask pointer having been initialized in
a random place earlier).

I had the cleanups (uncommited) in my tree, and just removed the
kfree() as per Christoph.
