[PATCH V2 2/3] regulators: Add definition of regulator_set_voltage_time() for !CONFIG_REGULATOR

[Viresh Kumar]

We already have dummy implementation for most of the regulators APIs for
!CONFIG_REGULATOR case and were missing it for regulator_set_voltage_time().

Found this issue while compiling cpufreq-cpu0 driver without regulators support
in kernel.

drivers/cpufreq/cpufreq-cpu0.c: In function âcpu0_cpufreq_probeâ:
drivers/cpufreq/cpufreq-cpu0.c:186:3: error: implicit declaration of function âregulator_set_voltage_timeâ [-Werror=implicit-function-declaration]

Fix this by adding dummy definition for regulator_set_voltage_time().
