Is that likely to happen before the merge window?

Hrm, I'd have expected this to return -EINVAL when stubbed.  I'd also
have expected regulator_set_voltage() to return -EINVAL mind you.  I
*suppose* that something that doesn't actually depend on regulator like
cpufreq might not care if the voltage really did change (I bet this was
added for cpufreq) but it's not awesome.
