From f1e10354fc2a12773e5e8efcf841380aa57d4aa5 Mon Sep 17 00:00:00 2001 From: Axel Lin Date: Sat, 5 Nov 2011 14:47:19 +0800 Subject: ASoC: wm9081: Fix reading wrong register for setting VMID 2*240k VMID Divider Enable and Select is controlled by BIT[2:1] of WM9081_VMID_CONTROL register (04h). Current code reads wrong register (WM9081_BIAS_CONTROL_1) for setting VMID 2*240k.
