From b87c464ea2c27005f592aaf351af40989f90f574 Mon Sep 17 00:00:00 2001 From: Trent Piepho Date: Wed, 25 Jul 2007 18:41:17 +0200 Subject: [PATCH] [ALSA] ca0106: remove extra commands in SPI DAC init sequence The init sequence set a number of registers more than once to different values. It's only necessary to set them once to their final values. It also never actually updated the digital attenuation settings.
