From 1c93c725d61642511f02a3293bcd7e694d0397d2 Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Thu, 5 Jun 2014 23:24:12 +0200 Subject: mfd: UCB1x00: Enable modular build 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.
