From cf6f1ff17f56c275424c5a341fc4d27ccbbfa71c Mon Sep 17 00:00:00 2001 From: Clemens Ladisch Date: Fri, 17 Jun 2011 08:18:35 +0200 Subject: [PATCH] ALSA: isight: adjust for new queueing API Since commit 13882a82ee16 (optimize iso queueing by setting wake only after the last packet), drivers are required to call fw_iso_context_queue_flush() after queueing a batch of packets. The missing call would have an effect only if the controller queue underruns, but then the DMA would stop completely.
