From d262a71957dcbe42e84e23aa4d3ca1c64bc10176 Mon Sep 17 00:00:00 2001 From: Vladimir Serbinenko Date: Tue, 28 Jan 2014 14:28:49 +0100 Subject: [PATCH] ibexpeak/azalia: Remove C4-register extended init. MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This sequence was derived from BD82X6X and on ibexpeak it inadvertently disables interrupts. In older kernels it wasn't a problem but in new kernel it makes codec probe fail.
