Subject: [PATCH resend 07/11] ASoC: soc-core: initialize component list
Date: 20 Aug 2019 14:05:16 +0900	[thread overview]
Message-ID: <87zhk4zazt.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>

It might return without initializing in error case.
In such case, uninitialized variable might be used at error handler.
This patch initializes all necessary variable before return.
