From a7433cff9ed8e7982de8e0f210f0325d0f3d1949 Mon Sep 17 00:00:00 2001 From: Linus Walleij Date: Wed, 26 Aug 2009 12:54:04 +0200 Subject: REGULATOR Handle positive returncode from enable This makes _regulator_enable() properly handle the case where a regulator is already on when you try to enable it. Currently it will erroneously handle positive return values as an error.
