Paul Gortmaker 0db03f3f0c drivers/mcb: do not set default Kconfig variable to modular
Coverage builds found this build fail in ARM ebsa110_defconfig:

    drivers: Introduce MEN Chameleon Bus

The above commit used "default m" which is wrong.  New drivers
should never be globally enabled with "default y/m".  Whether
this driver makes sense to build on ARM is an independent issue.

Here we delete the "default m" line, which is the equivalent of
"default n".

# MEN Chameleon Bus (MCB) support

menuconfig MCB
tristate "MCB support"
help
The MCB (MEN Chameleon Bus) is a Bus specific to MEN Mikroelektronik
FPGA based devices. It is used to identify MCB based IP-Cores within
an FPGA and provide the necessary framework for instantiating drivers
for these devices.
If build as a module, the module is called mcb.ko
if MCB
config MCB_PCI
tristate "PCI based MCB carrier"
default m
help
This is a MCB carrier on a PCI device. Both PCI attached on-board
FPGAs as well as CompactPCI attached MCB FPGAs are supported with
this driver.
If build as a module, the module is called mcb-pci.ko
