Subject: [PATCH 6/7] staging: bcm2835-audio: Deliver indirect-PCM transfer error
Date: Sun, 21 May 2017 21:02:57 +0200	[thread overview]
Message-ID: <20170521190258.1178-7-tiwai@suse.de> (raw)
In-Reply-To: <20170521190258.1178-1-tiwai@suse.de>

Now that the indirect-PCM transfer helper gives back an error, we
should return the error from ack callbacks.
