Subject: [PATCH resend 10/11] ASoC: soc-topology: use for_each_component_dais() at remove_dai()
Date: 20 Aug 2019 14:05:32 +0900	[thread overview]
Message-ID: <87tvaczazd.wl-kuninori.morimoto.gx@renesas.com> (raw)
In-Reply-To: <87a7c41lf1.wl-kuninori.morimoto.gx@renesas.com>

From: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com>

commit 52abe6cc1866a ("ASoC: topology: fix oops/use-after-free case
with dai driver") fixups remove_dai() error, but it is using
list_for_each_entry() for component->dai_list.

We already have for_each_component_dais() macro for it.
Let's use exising method.
