From 640b796f2ca88113bf2fefd380bc807092ce6fa1 Mon Sep 17 00:00:00 2001 From: Guennadi Liakhovetski Date: Thu, 28 Jan 2010 16:28:55 +0100 Subject: ASoC: remove bogus SLEEP mode from wm8978 driver Tests showed, that bit 6 of the WM8978_POWER_MANAGEMENT_2 register of wm8978 affects codec clocks. Being useless for suspend / resume, it cannot be used in bias-level control either. Remove this bit handling.
