From bd0dda744cdfb93a1907091c4540764593a28fa2 Mon Sep 17 00:00:00 2001 From: Charles Keepax Date: Thu, 3 Apr 2014 15:32:15 +0100 Subject: [PATCH] regulator: core: Add of_node_get to of_regulator_match Currently, of_regulator_match does not increment the reference count of the of_nodes it takes new references to. This could cause the node pointer held to be invalid, by the time it is passed to the regulator core. This patchs adds an of_node_get when we copy each of_node pointer into the match structure.
