Date: Tue, 02 Aug 2011 12:54:56 +0800 From: Axel Lin <axel.lin@...il.com> To: linux-kernel@...r.kernel.org Cc: Haojian Zhuang <haojian.zhuang@...vell.com>, Liam Girdwood <lrg@...com>, Mark Brown <broonie@...nsource.wolfsonmicro.com> 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.
