From mboxrd@z Thu Jan 1 00:00:00 1970 From: Ranjani Sridharan Subject: [PATCH] ASoC: SOF: Intel: hda: Initialize HDA controller after i915 init Date: Mon, 15 Jul 2019 13:34:52 -0700 Message-ID: <20190715203452.29997-1-ranjani.sridharan@linux.intel.com> Mime-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit Return-path: Received: from mga03.intel.com (mga03.intel.com [134.134.136.65]) (using TLSv1.2 with cipher ECDHE-RSA-AES256-GCM-SHA384 (256/256 bits)) (No client certificate requested) by alsa1.perex.cz (Postfix) with ESMTPS id 400D4F802BC for ; Mon, 15 Jul 2019 22:34:54 +0200 (CEST) List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Errors-To: alsa-devel-bounces@alsa-project.org Sender: "Alsa-devel" To: alsa-devel@alsa-project.org Cc: tiwai@suse.de, broonie@kernel.org, pierre-louis.bossart@linux.intel.com List-Id: alsa-devel@alsa-project.org On some platforms, sound card registration fails when a HDMI monitor is not connected. This is caused by a recent commit that switched the order in which the HDA controller and the i915 are initialized. Initializing the i915 before initializing the HDA controller fixes the problem.
