Takashi Iwai 9d4f4dc3cd ALSA: usb-audio: Fix last interface check for registration 
commit 39efc9c8a9 upstream.

The recent fix in commit 6392dcd1d0 ("ALSA: usb-audio: Register card
at the last interface") tried to delay the card registration until the
last found interface is probed.  It assumed that the probe callback
gets called for those later interfaces, but it's not always true; as
the driver loops over the descriptor and probes the matching ones,
it's not separately called via multiple probe calls.  This results in
the missing card registration, i.e. no sound device.

For addressing this problem, replace the check whether the last
interface is processed with usb_interface_claimed() instead of the
comparison with the probe interface number.

Fixes: 6392dcd1d0 ("ALSA: usb-audio: Register card at the last interface")

README 

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.
