From 115c7254882ceb965deb05510128464fef06fbfb Mon Sep 17 00:00:00 2001 From: Julia Lawall Date: Thu, 8 Sep 2016 02:35:23 +0200 Subject: ASoC: constify snd_pcm_ops structures Check for snd_pcm_ops structures that are only stored in the ops field of a snd_soc_platform_driver structure or passed as the third argument to snd_pcm_set_ops. The corresponding field or parameter is declared const, so snd_pcm_ops structures that have this property can be declared as const also. The semantic patch that makes this change is as follows: (http://coccinelle.lip6.fr/) // @r disable optional_qualifier@ identifier i; position p; @@ static struct snd_pcm_ops i@p = { ... }; @ok1@ identifier r.i;
