Hi all, After merging the regulator tree, today's linux-next build (x86_64 allmodconfig) failed like this: drivers/built-in.o: In function `ltc3589_probe': ltc3589.c:(.text+0xccf24): undefined reference to `devm_regmap_init_i2c' drivers/built-in.o: In function `ltc3589_driver_init': ltc3589.c:(.init.text+0x9ebc): undefined reference to `i2c_register_driver' drivers/built-in.o: In function `ltc3589_driver_exit': ltc3589.c:(.exit.text+0x2d1): undefined reference to `i2c_del_driver' Caused by commit 3eb2c7ecb7ea ("regulator: Add LTC3589 support"). Clearly some dependencies are incorrect. Presumably the required interfaces are in modules for this build. I have used the regulator tree from next-20140526 for today. -- Cheers, Stephen Rothwell sfr@canb.auug.org.au
