From 13aeaf68019d297be79c99f828c2a9d6affef06b Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Tue, 25 Feb 2014 07:53:47 +0100 Subject: ALSA: hda - Create own device struct for each codec As the HD-audio is treated individually in each codec driver, it's more convenient to assign an own struct device to each codec object. Then we'll be able to use dev_err() more easily for each codec, for example. For achieving it, this patch just creates an object "hdaudioCxDy". It belongs to sound class instead of creating a new bus, just for simplicity, at this stage. No pm ops is implemented in the device struct level but currently it's merely a container. The PCM and hwdep devices are now children of this codec device.
