From a171e782a97d4ba55d7fa02f9a46904288b2c229 Mon Sep 17 00:00:00 2001 From: Axel Lin Date: Tue, 27 Mar 2012 15:17:26 +0800 Subject: [PATCH] regulator: wm831x-dcdc: Fix the logic to choose best current limit setting Current code in wm831x_buckv_set_current_limit actually set the current limit setting greater than specified range. Fix the logic in wm831x_buckv_set_current_limit to choose the smallest current limit setting falls within the specified range.
