From 988f0664779674c7c06252a6d549eee8debd5d76 Mon Sep 17 00:00:00 2001 From: Karsten Wiese Date: Tue, 22 Apr 2008 12:52:15 +0200 Subject: [ALSA] ice1724.c: toggle "chip reset" and "eeprom based setup" sequence Let "chip reset" become first. Increasement of the "chip reset" related timeout leads to correctly read eeprom's contents here.
