From f918e1697b1a8f2f26a4813db053cfbcafc48046 Mon Sep 17 00:00:00 2001 From: Mengdong Lin Date: Fri, 19 Aug 2016 18:12:46 +0800 Subject: [PATCH] ASoC: topology: ABI - Add sig_bits to stream caps Kernel struct snd_soc_pcm_stream, SoC PCM stream information, needs this field. Although current topology users don't configure this, we define it for future extension.
