>>> sound/pci/mixart/mixart_core.c:39:19: sparse: sparse: incorrect type in argument 1 (different address spaces) @@     expected void


Hmm, I would like to fix this if I can - but the patch is a DT for 
mips/econet and didn't touch anything in sound/pci so it seems like the 
blame was incorrect. But I don't know well enough to say, so if anyone 
knows how this patch might be related, please let me know.


Thanks,

Caleb
