From 2428a2ed6a7cbc7be6db5c70c3838a4bf0de9f48 Mon Sep 17 00:00:00 2001 From: Devin Heitmueller Date: Sun, 27 Jun 2010 17:40:42 -0300 Subject: [PATCH] [media] au8522: cleanup code which disables audio decoder Cleanup the routine which disables the audio decoder. In particular, the i2s output was being shut off but the audio processor itself was not, resulting in more power being consumed than needed.
