From b0a23b8b36e1fb754dcbdfe622e5ca5ded2f188b Mon Sep 17 00:00:00 2001 From: Lars-Peter Clausen Date: Mon, 6 Jan 2014 14:19:09 +0100 Subject: ASoC: fsl: Don't set unused struct snd_pcm_hardware fields The ASoC core assumes that the PCM component of the ASoC card transparently moves data around and does not impose any restrictions on the memory layout or the transfer speed. It ignores all fields from the snd_pcm_hardware struct for the PCM driver that are related to this. Setting these fields in the PCM driver might suggest otherwise though, so rather not set them.
