Well, we would need to look at what the drivers were doing and figure out something sensible - it really depends why they're trying to set the regulator and what would happen if it doesn't work.
For example, few cpufreq drivers are calling it during frequency transition and are checking return value as well.. And fail if it failed.
One way out might be checking if pointer to regulator is valid or not and only call it if pointer is not NULL..
No, as I've explained repeatedly NULL is a perfectly valid regulator and that's not going to work reliably. As I've previously requested please think about what happens to cpufreq if we fail to ramp voltages.
