You may get further e-mails resulting from automated or manual testing and review of the tree, please engage with people reporting problems and send followup patches addressing any issues that are reported if needed. If any updates are required or you are submitting further changes they should be sent as incremental updates against current git, existing patches will not be replaced. Please add any relevant lists and maintainers to the CCs when replying to this mail. Thanks, Mark >From d89564efe79419a093e966a959bf5ba2c94e693f Mon Sep 17 00:00:00 2001 From: Matthias Kaehlcke <mka@chromium.org> Date: Wed, 14 Sep 2016 09:52:07 -0700 Subject: [PATCH] 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.
