From 3764806440149ea9024dff039497d1e45d6ed027 Mon Sep 17 00:00:00 2001 From: Charles Keepax Date: Thu, 3 Apr 2014 15:32:16 +0100 Subject: regulator: core: Add helper to put of_nodes from matches As of_regulator_match will take an of_node reference to each matched regulator, it makes sense to provide a helper to put all those references. This patch does that.
