Hi all, After merging the regulator tree, today's linux-next build (x86_64 allmodconfig) failed like this: lp872x.c:(.text+0xb0699): undefined reference to `devm_regmap_init_i2c' drivers/built-in.o: In function `lp872x_driver_init': lp872x.c:(.init.text+0x81ac): undefined reference to `i2c_register_driver' drivers/built-in.o: In function `lp872x_driver_exit': lp872x.c:(.exit.text+0x37e): undefined reference to `i2c_del_driver' CONFIG_I2C=m in this build. Caused by commit 809d310c7e69 ("regulator: lp872x: Don't allow modular build") but that was done to fix a different build problem. I have used the regulator tree from next-20120619 again for today. -- Cheers, Stephen Rothwell sfr@canb.auug.org.au
