From e5241a8c4b22b678dd9b07527ba9f178f02e160e Mon Sep 17 00:00:00 2001 From: Richard Fitzgerald Date: Wed, 25 Nov 2015 13:00:24 +0000 Subject: [PATCH] ALSA: compress: Pass id string to snd_compress_new Make snd_compress_new take an id string (like snd_pcm_new). This string can be included in the procfs info. This patch also updates soc_new_compress() to create an ID based on the stream and dai name, as done for PCM streams.
