Hi Mans,

I've tried to apply your patch on a next-20160112 branch to test it but it
failed. I've also looked at the for-next branch of the SPI sub-system git
tree.

It seems that one issue occurred within a chunk patching the atmel_spi_setup()
function. Please see below.

There is no 'else' statement in the source code I'm looking at.

Best regards,
