From 907fe36a2cd572fe58d98be01457b945c47b996e Mon Sep 17 00:00:00 2001 From: Lars-Peter Clausen Date: Tue, 22 Apr 2014 13:23:14 +0200 Subject: ASoC: Move standard kcontrol helpers to the component level After moving the IO layer inside ASoC to the component level we can now easily move the standard control helpers also to the component level. This allows to reuse the same standard helper control implementations for other components.
