The UCB1200 / UCB1300 driver uses the MCP_SA11X0 driver, which can be a loadable module, but this results in a link error when UCB1200 itself is built-in:
drivers/built-in.o: In function `ucb1x00_io_set_dir': :(.text+0x4a364): undefined reference to `mcp_reg_write' drivers/built-in.o: In function `ucb1x00_io_write': :(.text+0x4a3dc): undefined reference to `mcp_reg_write' drivers/built-in.o: In function `ucb1x00_io_read': :(.text+0x4a400): undefined reference to `mcp_reg_read' drivers/built-in.o: In function `ucb1x00_adc_enable': :(.text+0x4a460): undefined reference to `mcp_enable' ...
This can easily be resolved by making CONFIG_MCP_UCB1200 itself a tristate option, since that causes Kconfig to track the dependency correctly.
