From f959dee9c7b5e36a139e1e8fcfedbddfea65d00d Mon Sep 17 00:00:00 2001 From: Mark Brown Date: Tue, 31 Jan 2012 16:16:47 +0000 Subject: ASoC: wm_hubs: Push check for idle_bias_off out into drivers For later wm_hubs devices we have much less need to keep the biases up even when using single ended line outputs so flag idle_bias_off for everything except the WM8993 and WM8994.
