From c4f2a46e0dfee336ce7016cd62608097f15367b8 Mon Sep 17 00:00:00 2001 From: Amaury Pouly Date: Tue, 23 Jul 2013 14:12:08 +0200 Subject: imx233: revert volumes to 1dB resolution Using a better resolution causes havoc in the user interface because it doesn't properly handle steps and people start to believe I am responsible for all this mess.
