From 586e1a1763d34bd256f3f1e77293d8386e4871d2 Mon Sep 17 00:00:00 2001 From: Haojian Zhuang Date: Fri, 6 May 2011 17:21:23 +0800 Subject: [PATCH] mfd: Avoid to use constraint name in 88pm860x regulator driver Avoid to use constraint name in regulator driver. So use regulator id is used instead in platform driver.
