Subject: [PATCH] ASoC: blackfin: use samples to set silence
Date: Fri, 18 Jul 2014 16:14:57 +0800 [thread overview]
Message-ID: <1405671297-17792-2-git-send-email-scott.jiang.linux@gmail.com> (raw)
In-Reply-To: <1405671297-17792-1-git-send-email-scott.jiang.linux@gmail.com>
The third parameter for snd_pcm_format_set_silence needs the number
of samples instead of sample bytes.
