From 47e039413cacee70229ebbf6de5a8e3b27e6f057 Mon Sep 17 00:00:00 2001 From: Lars-Peter Clausen Date: Fri, 23 Jan 2015 16:21:36 +0100 Subject: ASoC: Add support for allocating AC'97 device before registering it In some cases it is necessary to before additional operations after the device has been initialized and before the device is registered. This can for example be resetting the device. This patch introduces a new function snd_soc_alloc_ac97_codec() which is similar to snd_soc_new_ac97_codec() except that it does not register the device. Any users of snd_soc_alloc_ac97_codec() are responsible for calling device_add() manually.

Before commit 6794f709b712 ("ASoC: ac97: Drop delayed device registration") the device was only registered after the probe function of the CODEC driver had finished running, but starting with the mentioned commit the device is registered as soon as snd_soc_new_ac97_codec() is called. This causes the touchscreen driver to no longer work. Modify the CODEC drivers to use snd_soc_alloc_ac97_codec() instead of snd_soc_new_ac97_codec() and make sure that the AC'97 device is reset before the snd_ac97 device gets registered.
