Strange. I just applied only this patch and the build still works
on my system. I don't see any reason why this change of the
menuconfig options from tristate to bool would cause the
problem you are seeing.

I do see a problem in the Kconfig for the adl_pci7296 driver.

Based on the error message above, it requires COMEDI_8255. But that
option is not listed as a depends or select. I noticed a couple other
comedi drivers with the same issue.

Regards,
Hartley
