From 19c98825941cb10b59c9953665fc4495bc82c0ae Mon Sep 17 00:00:00 2001 From: Linus Walleij Date: Fri, 11 Mar 2011 16:26:18 +0100 Subject: regulator: switch the ab3100 to use enable_time() Acked-by: Mark Brown This switches the ab3100 core to use the enable_time() infrastructure from the regulator core.
