[PATCH 5.4 153/191] regulator: axp20x: Fix axp20x_set_ramp_delay
From: Greg Kroah-Hartman
Date: Tue Jan 07 2020 - 16:02:14 EST
From: Axel Lin <axel.lin@xxxxxxxxxx>
commit 71dd2fe5dec171b34b71603a81bb46c24c498fde upstream.
Current code set incorrect bits when set ramp_delay for AXP20X_DCDC2,
fix it.
Fixes: d29f54df8b16 ("regulator: axp20x: add support for set_ramp_delay for AXP209")
