From b49d15d138aa4632f35a2db93dee775d920f3653 Mon Sep 17 00:00:00 2001 From: NeilBrown Date: Fri, 7 Aug 2015 13:45:25 +1000 Subject: [PATCH] twl4030_charger: fix compile error when TWL4030_MADC not available. We can only use the madc to check for 'ac' availability if the madc has been compiled in. If not: assume always using USB.
