Today (even with the above patch included) I got these errors from the
x86_64 allmodconfig build:

tps65910.c:(.text+0xf4140): undefined reference to `i2c_master_send'
drivers/built-in.o: In function `tps65910_i2c_read':
tps65910.c:(.text+0xf41d2): undefined reference to `i2c_transfer'
drivers/built-in.o: In function `tps65910_i2c_init':
tps65910.c:(.init.text+0xcb83): undefined reference to `i2c_register_driver'
drivers/built-in.o: In function `tps65910_i2c_exit':
tps65910.c:(.exit.text+0x6e0): undefined reference to `i2c_del_driver'

I have used the voltage tree from next-20110509 again today.
