Hi Samuel, After merging the mfd tree, today's linux-next build (x86_64 allmodconfig) failed like this: drivers/built-in.o: In function `wm8400_i2c_probe': wm8400-core.c:(.text+0x100165): undefined reference to `devm_regmap_init_i2c' drivers/built-in.o: In function `wm8400_module_init': wm8400-core.c:(.init.text+0xb43c): undefined reference to `i2c_register_driver' drivers/built-in.o: In function `wm8400_module_exit': wm8400-core.c:(.exit.text+0x655): undefined reference to `i2c_del_driver' Probably caused by commit 96cd102ae039 ("mfd: Don't support non-modular wm8400 build") which was introduced to fix other problems. In this build, CONFIG_I2C=m and CONFIG_REGMAP_I2C=m. I have used the mfd tree from next-20120511 again for today. -- Cheers, Stephen Rothwell sfr@xxxxxxxxxxxxxxxx
