From 88a60e552f114ae34796604575239fb196658067 Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Mon, 8 Sep 2014 13:14:05 +0200 Subject: [PATCH] ASoC: simple-card: fix regression in clock rate lookup Commit 7c7b9cf53d284f ("ASoC: simple-card: fixup cpu_dai_name clear case") changed the way that "sound-dai" properties are handled, which leads to the clock frequency not being picked up from the node that the phandle points to, as correctly identified by gcc with this warning: sound/soc/generic/simple-card.c: In function 'asoc_simple_card_sub_parse_of': sound/soc/generic/simple-card.c:165:7: warning: 'node' may be used uninitialized in this function [-Wmaybe-uninitialized] This restores the previous behavior by using the node from of_parse_phandle_with_args() that was previously being returned from of_parse_phandle().
