Subject: [PATCH 3/6] regulator: check for init_data on registration
Date: Fri, 19 Sep 2008 18:39:47 +0100	[thread overview]
Message-ID: <1221845987.6892.137.camel@odin> (raw)

Since it is now mandatory to supply constraints via init_data on device
registration check for that when registering, saving us from oopsing
later on.
