From: Matthias Kaehlcke Date: Wed, 14 Sep 2016 16:52:07 +0000 (-0700) Subject: regulator: core: Don't skip set_voltage_time when ramp delay disabled X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=d89564efe79419a093e966a959bf5ba2c94e693f;p=linux-beck.git regulator: core: Don't skip set_voltage_time when ramp delay disabled The current code assumes that only the ramp_delay is used to determine the time needed for the voltage to stabilize. This may be true for the calculation done by regulator_set_voltage_time_sel(), however regulators can implement their own set_voltage_time_sel() op which would be skipped if no ramp delay is specified. Remove the check in _regulator_do_set_voltage(), the functions calculating the ramp delay return 0 anyway when the ramp delay is not configured.
