that's because the cpufreq-cpu0 driver (that's built-in) requires the
tsp65217 regulator driver that is compiled as a module (and not
available during boot).

While it's only a warning and it goes away when the rootfs is mounted
(and the tps65217_regulator module is loaded), it's annoying and it
spams the syslog.

** Affects: linux (Ubuntu)
     Importance: Undecided
