Subject: [PATCH 1/3] regulator: lp8788-ldo: Use platform_register/unregister_drivers()
Date: Wed, 2 Dec 2015 17:32:51 +0100 [thread overview]
Message-ID: <1449073973-12863-1-git-send-email-thierry.reding@gmail.com> (raw)
From: Thierry Reding <treding@nvidia.com>
These new helpers simplify implementing multi-driver modules and
properly handle failure to register one driver by unregistering all
previously registered drivers.
