Hi,

I'm trying to use device-tree on my at91sam9263 based board. Works so far, but 
I'm getting those BUGs
for each SPI device being probed (2 in my case)

Currently, I can't figure out why this happens. It's a plain v3.14 kernel with 
some own patches which don't affect SPI.

Best regards,
Alexander
