From 1561f09a2f91bc258a72225f919807c9e51c8290 Mon Sep 17 00:00:00 2001 From: Jaya Kumar Date: Mon, 19 Jun 2006 15:06:14 +0200 Subject: [ALSA] AD1888 suspend/resume fix This patch adds a write to an undocumented register, 0x60 Extended Codec Register Page in the AD1888 codec. It is neccessary in order to make suspend/resume work with the AD1888.
