[PATCH] regulator: of: Lower the severity of the error with no container

From: Mark Brown
Date: Wed Oct 08 2014 - 18:10:33 EST

Description of regulators should generally be optional so if there is no
DT node for the regulators container then we shouldn't print an error
message. Lower the severity of the message to debug level (it might help
someone work out what went wrong) and while we're at it say what we were
looking for.
