regulator: pwm: Fix calculation of voltage-to-duty cycle
With following equation for calculating voltage_to_duty_cycle_percentage 100 - (((req_uV * 100) - (min_uV * 100)) / diff); we get 0% for max_uV and 100% for min_uV. Correcting this to ((req_uV * 100) - (min_uV * 100)) / diff; to get proper duty cycle. Signed-off-by: Laxman Dewangan <ldewangan@nvidia.com> Signed-off-by: Mark Brown <broonie@kernel.org>
