You need to disable the SPI driver option in your kernel configuration.

$ make menuconfig

Kernel/Library/Defaults Selection  --->

Customise Kernel Settings -->

characeter Devices -->

SPI support -->

and make sure it is disabled.

As a general rule, if you run "make menuconfig" and it gives displays an
option on the command line like

"SPI Support (Y/N) [N]"

You shold press enter, selecting the default, which is no.  If in doubt,
leave it out!

Regards,

John
