From c16a7428912350a28f51df48c5f738523b1ecd8b Mon Sep 17 00:00:00 2001 From: Mark Brown Date: Wed, 10 Oct 2012 20:24:23 +0900 Subject: [PATCH] ASoC: wm8770: Remove unneeded bias level manipulation Since the device is now idle_bias_off these never have any useful effect, the device will be brought to _OFF when idle, and will at best leave it powered for longer.
