From f1aac484f705007caf0d7c256a1a29506600cae3 Mon Sep 17 00:00:00 2001 From: Mark Brown Date: Mon, 5 Dec 2011 15:17:06 +0000 Subject: [PATCH] ASoC: Take a pm_runtime reference on DAPM devices that are enabled As for PCMs take a runtime power management reference to devices that are in a non-off bias, avoiding the need to do this in individual drivers.
