Mark, let me know whether you'd take this via your tree or may I take via mine (with a minor correction of the subject line).
I don't have the patch... in fact, having found it in list archives I see there's also a SPI patch I'll have to go hunting for so I guess I'll apply this one when I find that :( Christoph, please CC maintainers.
FWIW, the driver sets the 31bit (!) DMA mask, and that's the likely reason of GFP_DMA passed there in the original code.
Likely, yes.
