From 31d2350d602511efc9ef626b848fe521233b0387 Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Mon, 18 Feb 2019 14:38:06 +0100 Subject: [PATCH] ALSA: ac97: Fix of-node refcount unbalance ac97_of_get_child_device() take the refcount of the node explicitly via of_node_get(), but this leads to an unbalance. The for_each_child_of_node() loop itself takes the refcount for each iteration node, hence you don't need to take the extra refcount again.
