From a180ba45b1cf630b3bd5912ce235b2ee16606b8e Mon Sep 17 00:00:00 2001 From: Bhumika Goyal Date: Thu, 3 Aug 2017 21:30:19 +0530 Subject: ASoC: codecs: add const to snd_soc_codec_driver structures Declare snd_soc_codec_driver structures as const as they are only passed as an argument to the function snd_soc_register_codec. This argument is of type const, so declare the structures with this property as const. In file codecs/sn95031.c, snd_soc_codec_driver structure is also used in a copy operation along with getting passed to snd_soc_register_codec. So, it can be made const too.
