Subject: [PATCH v4 3/4] ASoC: SOF: pcm: add .ack callback support
Date: Fri, 19 Nov 2021 17:08:51 -0600 [thread overview]
Message-ID: <20211119230852.206310-4-pierre-louis.bossart@linux.intel.com> (raw)
In-Reply-To: <20211119230852.206310-1-pierre-louis.bossart@linux.intel.com>
From: Ranjani Sridharan <ranjani.sridharan@linux.intel.com>
Add the indirections required at the core level for platform-specific
operations on ack.
Note that on errors in the .ack the ALSA core will restore the
previous appl_ptr.
