From b13296d0701b90fa8eae5cb6b79c7a2d7a75d3b2 Mon Sep 17 00:00:00 2001 From: Axel Lin Date: Thu, 17 May 2012 13:06:18 +0800 Subject: [PATCH] regulator: ab3100: Use regulator_map_voltage_iterate() regulator_map_voltage_iterate() is for drivers implementing set_voltage_sel() and list_voltage() to use it as their map_voltage() operation. In this case, regulator_map_voltage_iterate() happen to be doing the same thing as ab3100_get_best_voltage_index() function. So we can use it to replace ab3100_get_best_voltage_index() function.
