Kernel does not compile

[zem]

At the moment I do not know how to fugure out which menuconfig entry causes this error:

  MODPOST vmlinux.o
drivers/built-in.o: In function `cht_wc_probe':
/usr/src/Pocket-Ubuntu-kernel/drivers/mfd/intel_soc_pmic_chtwc.c:191: undefined reference to `devm_mfd_add_devices'
Makefile:997: recipe for target 'vmlinux' failed
make[1]: *** [vmlinux] Error 1
make[1]: Leaving directory '/usr/src/Pocket-Ubuntu-kernel'
debian/ruleset/targets/common.mk:295: recipe for target 'debian/stamp/build/kernel' failed
make: *** [debian/stamp/build/kernel] Error 2
root@localhost:/usr/src/Pocket-Ubuntu-kernel# git remote -v

It is strange that there is no useable .config is provided for the kernel and it is definately a bug that this config breaks the build.
