From f4333203ec933f9272c90c7add01774ec2cf94d3 Mon Sep 17 00:00:00 2001 From: Lars-Peter Clausen Date: Mon, 16 Jun 2014 18:13:02 +0200 Subject: ASoC: Move name and id from CODEC/platform to component The component struct already has a name and id field which are initialized to the same values as the same fields in the CODEC and platform structs. So remove them from the CODEC and platform structs and used the ones from the component struct instead.
