The call of snd_hdac_bus_add_device() is needed only for registering the codec onto the bus caddr_tbl[] that is referred essentially only in the unsol event handler. That is, the reason of this call and the release by the counter-part function snd_hdac_bus_remove_device() is just to assure that the unsol event gets notified to the codec. But the current implementation of the unsol notification wouldn't work properly when the codec is still in a premature init state. So this patch tries to work around it by delaying the caddr_tbl[] registration at the point of snd_hdac_device_register(). Also, the order of snd_hdac_bus_remove_device() and device_del() calls are shuffled to make sure that the unsol event is masked before deleting the device.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
