Subject: [PATCH] ASoC: SOF: pcm: add .ack callback support
Mime-version: 1.0

Git-commit: 4a39ea3f07f14f21a6b97e78c972f71fc5761d3a
Patch-mainline: v5.17-rc1
References: jsc#PED-850
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.
