From 3cb6dcfa44e883412f8df2f2b1917b0d359f3ec4 Mon Sep 17 00:00:00 2001 From: Axel Lin Date: Fri, 9 Jan 2015 17:43:06 -0800 Subject: [PATCH] Input: regulator-haptic - simplify code All the use cases in this driver has a regulator_haptic_toggle() call after regulator_haptic_set_voltage(). So make regulator_haptic_set_voltage() call regulator_haptic_toggle() to simplify the code.
