Be prepared for the fallout. There are test farms running bind/unbind cycles
on random drivers.

IIRC, I did test unbind.
The real and productive fix is to change "bool" to "tristate" in Kconfig.
All of these "make ... explicitly non-modular" may have to be reverted again
when our kernels become too big to boot.
