From c1b4d1c7774189002bc08766ec10e339dfbc98d6 Mon Sep 17 00:00:00 2001 From: Lars-Peter Clausen Date: Sat, 25 Oct 2014 20:25:56 +0200 Subject: ASoC: Use generic control handlers for S8 control Commit f227b88f0fce ("ASoC: core: Add signed register volume control logic") added support for signed control to the generic volsw control handler. This makes it possible to use them for the S8 control as well, rather than having to use a custom control handler implementation.
