From e69c499790a35ef5ad164fd99f0b691e138640da Mon Sep 17 00:00:00 2001 From: Axel Lin Date: Tue, 2 Aug 2011 12:54:56 +0800 Subject: [PATCH] regulator: Ensure enough enable time for max8649 Integer division may truncate the result, thus max8649_enable_time() may return slightly shorter enable time. This patch fixes it.
