Subject: [PATCH] regulator: Hoist struct regulator_dev out of core to fix notifiers

From: Mark Brown <[email-masked]>
Date: Wed, 21 Jan 2009 14:08:40 +0000

Commit 872ed3fe176833f7d43748eb88010da4bbd2f983 caused regulator drivers
to take the struct regulator_dev lock themselves which requires that the
struct be visible to them. Band aid this by making the struct visible.
